Parametric control to a type of descriptor quasi-linear high-order systems via output feedback☆
Introduction
In the real world, many dynamical models of practical applications are quasi-linear, including spacecraft rendezvous [5], attitude control of combined spacecraft [18], robotic systems [28], and so on. Simultaneously, quasi-linear systems maintain strong coupling and highly nonlinear characteristics but in a linear format, which can be regarded as the link and bridge between linear systems and general nonlinear systems. In the past, the quasi-linear system has been intensively considered in the literature (see [2], [14], [15], [20], [22], [25], [26], [32] and the references therein).
Note that quasi-linear high-order systems can be commonly used for the modeling of synchronization of chaotic systems [12], jerk system [21], wind-induced vibrating comfort [27], etc., which has great value in engineering applications, however, descriptor quasi-linear high-order system, which can represent static and dynamic processes of practical systems, has been not investigated in the recent researches.
Gu and his team present an effective approach to design the static output feedback and the dynamic compensator for linear time-varying systems [9], [13] and quasi-linear systems [5], [6], [7], [8], [10], [11], [12], which provides the fundamental to deal with the parametric design of output feedback for descriptor quasi-linear high-order systems.
In this study, a parametric approach, based on the solution of HGSEs, is proposed to design output feedback for descriptor quasi-linear high-order systems such that the completely parameterized solution of output feedback is established. With the proposed parametric approach, the closed-loop system yields a linear constant form with an expected eigenstructure. Simultaneously, it is more simple and easy to maintain the regularity of closed-loop systems. Additionally, the parametric approach can offer free parameters to provide flexibility and degrees of design freedom in the design process. Compared with the related result in [31], this paper focuses on descriptor quasi-linear high-order systems and obtains the more explicit and unified expressions of output feedback gain matrices, it also effectively maintains the regularity of the closed-loop system.
The remaining part of this paper is respectively organized as follows. Section 2 presents the problem formulation of descriptor quasi-linear high-order systems with output feedback, and provides some preliminary results. In Section 3, parametric approach is proposed to establish the complete parameterization form of output feedback for two cases. A synchronization problem of Genesio–Tesi and Coullet systems is given to prove the effectiveness of parametric approach in Section 4. Section 5 draws the conclusions.

Conclusions
In this research, a parametric approach has been investigated to design the output feedback controller for descriptor quasi-linear high-order systems. The presented parametric approach has provided the completely parametric solution of the output feedback controller such that the closed-loop system has the expected eigenstructure. Note that the arbitrary parameter Z can provide the flexibility and degrees of design freedom to reduce the computation load and realize systems optimization.
