Some cutting-edge progress and results have been done in this particular area related to frequency domain analysis and design of nonlinear systems based on the Volterra series. Several are as follows:

(1) A benchmark parametric characteristic approach-nCOS (initially OFRF)

For nonlinear analysis and design in the frequency domain, I systematically proposed and developed this method, which presents an explicit analytical structure and expression of the output spectrum of nonlinear systems with respect to model parameters of interest (both linear and/or nonlinear components), frequency variable, and excitation amplitude (which are referred to as characteristic parameters) [A1.1-A1.11]. To this aim, I proposed two important operators for abstracting parametric characteristics 2006 [A1.1], and from parameter characteristics to frequency response functions (GFRF or OFRF) there are explicit invertible mapping relationships [A1.4]. Both analytical calculation and numerical methods are therefore developed named as OFRF (output frequency response function) initially or nCOS (nonlinear characteristic output spectrum) method later, based on the parametric characteristics. The first result providing the benchmark technical methods was published in 2006, strengthened or demonstrated in 2008, 2009, 2012, 2014, 2015, 2016, and most results were summarized into a monograph in 2015. Some works done by others later are following these technical lines.

(2) General and specific parametric convergence bounds (PCB) guiding the convergence of Volterra series expansion to a nonlinear system: Parametric Convergence Bounds & Parametric Convergence Margins

This was systematically developed in recent years with results published in 2013, 2014, 2015, 2017. These results can clearly say at what parametric range and what frequency range a given nonlinear system has a convergent Volterra series expansion. On the other hand, the results indicate also the appearance of complicated non-Volterra nonlinear dynamics such as chaos or bifurcation with a specific and explicit parameter range. These results solve the long lasting fundamental issue related to the application of Volterra series based methods. Technically, these results adopted the general parametric characteristic approach which was applied to the bound evaluation of output frequency response function of nonlinear systems in 2007, 2008, 2009.

(3) Applications to vibration control and signal processing: Exploring nonlinear benefits in Engineering

I started the study on “Exploring nonlinear benefits in engineering” ever since 2005 through a series of application of the methods above for nonlinear vibration control, nonlinear damping design, system identification, fault detection and so on. In vibration control, it is theoretically shown that nonlinear damping has very good advantage over linear damping with results published in 2006, 2008, 2009, 2011, 2013. It is for the first time revealed that the output frequency response would take an alternating series with respect to the concerned characteristic parameters for convergence and beneficial effect 2011 (based on the parametric characteristic approach) [A3.2]. Some novel output frequency characteristics were also clearly discussed 2010 [A3.3]. I developed a general technique for easily considering nonlinear damping effect, i.e., the effect for w<1, w=1 and w>1, well with the frequency domain approach above 2009 [A3.4]. It is noticed that, the method was well used in many other publications later on.

In recent years, we focus more on “Employing nonlinear benefits” in vibration control. The one issue is about how to realize beneficial nonlinearity in vibration control. It is known theoretically from out past research studies that some special nonlinearity can take very beneficial role in vibration control [A3.1-8]. Realization of these beneficial nonlinearities using active control methods would always meet some drawbacks such as energy /development /manufacturing /maintenance cost and/or actuators’ saturation etc. The best way is of course to achieve these nonlinearities at system or structure design stage using purely passive ways.

To this aim, we developed a bio-inspired limb-like or X-shaped structure approach ever since 2010 starting from a MSC thesis [B1.12]. It is noticed that animal or insect can always have very good body control during walking, running or jumping on even rough terrain. Their leg or limb skeleton usually takes very similar X-like, Z-like, quadrilateral shape, triangle shape, or any other similar shapes. This structure or its variants (with quadrilateral or polygon or triangle shape) can also be found in cranial bone and materials etc. These greatly motivate our current research efforts. It is revealed that the bio-inspired X-shaped structure can provide very beneficial nonlinear stiffness and damping characteristics [B.1.1, B1.6-11]] and can be applied extensively to various critical engineering issues, including vibration control [B1.1- B1.3, B1.13], energy harvesting [B3.1-4], and sensor design [B2.1-3] etc. Even though in active vibration control, the bio-inspired nonlinear dynamics can also help save energy cost [B1.2]. Robotic design benefits from the bio-inspired passive structure for advantageous body suspension as well. Potentially, the X-shaped structure approach presents an innovative technology to extensive engineering issues for vibration control. Based on these, a novel human body inspired vibration isolation system is also proposed for the first time in [B1.14], which is shown to be capable of presenting beneficial passive adjustable nonlinear stiffness, nonlinear damping and nonlinear inertia (or equivalent mass) simultaneously!

The X-shaped structure is inspired from animal leg/limb skeleton and takes a truss or scissor-like shape as mentioned above, which is already adopted in many engineering practices as different supporting structures. The joint of the X-shaped structure can be rotational joints with or without bearings or just rotational joint with elastic materials. There are many different forms in practical designs. However, it should be emphasized that, the fantastic nonlinear stiffness and damping characteristics are only known recently due to the series of pioneering works done by us, and there are still more amazing nonlinear dynamic features yet to be explored. This is similar to the fact that we are familiar with and even use our brain or body to do many things everyday but we really understand them a little!

The quasi-zero or zero-stiffness based vibration sensors:

A novel concept for absolute vibration displacement measurement; The quasi-zero or zero-stiffness with passive structure design is innovatively explored and employed which can create an absolute stable point in a broadband frequency domain and thus can be employed for vibration measurement, not only in static environments but also in moving platforms. This presents an innovative way to solve the issue for absolute vibration displacement measurement existing in the related field for many years.

Vibration signals based fault detection or diagnosis is done recently. We focus on development of fault diagnosis methods for complex structures with least prior knowledge, less testing data and other practical requirements. A recent work is done for bolt loosening of a satellite-like structure with a “virtual beam” approach, which actually presents a nonlinear feature dynamics based method under further investigation now. We are also developing some new fault-related nonlinear features by using our research results in the frequency-domain nonlinear analysis and design.

We have interest in development of robust control theory or methods in general to solve critical theoretical and/or practical issues focusing more on application oriented control methods [D.1-5]. For system identification, we developed a new robust control approach, which casts the traditional identification problem with input output data into a robust control or robust output feedback control problem and thus achieve more powerful and robust identification performance [D.7-8].
