考虑控制器在实现时其参数偏离原设计值发生摄动的情况,以H_∞为性能指标,提出一种基于Delta算子理论的永磁直线同步电动机非脆弱H_∞速度伺服控制器的设计方法。在此基础上把所设计的控制器与基于传统Z变换方法以及基于连续系统模型所设计的控制器进行比较。通过对系统闭环极点的分析,表明在快速采样的情况下,基于Delta算子理论所设计的非脆弱H_∞速度伺服控制器能保证闭环控制系统稳定而且满足所期望的H_∞性能指标,具有较好的跟随给定和抗干扰能力,而基于传统Z变换方法所设计的控制器将使闭环控制系统不稳定。而且当采样周期趋近于零时,基于Delta算子理论所设计的控制器参数趋近于基于连续系统模型所设计的控制器参数。

International Conference on Control, Automation, Robotics and Vision (ICARCV)

This paper studies the fixed-order controllers design problem for multi-input-multi-output (MIMO) systems. Polynomial methods are employed to design a controller that guarantees all the closed-loop poles reside within given D-stability regions. An H infin optimization approach is proposed to minimize the interaction between different channels of the MIMO system. Sufficient conditions for the existence of such a fixed-controller is established by using the linear matrix inequalities (LMIs) approach.

In the framework of multi-objective control, this paper presents a mixed H-2/H-infinity dynamic output feedback control strategy to the network remote control system with measurement data missing and control data missing. Via matrix inequality method, the sufficient for existence of the dynamic output feedback controller, guaranteeing the closed-loop system has H-2 and H-infinity performance simultaneously, is given. A novel arithmetic is put forward to optimize the controller performance via SLPMM (sequentially linear programming matrix method). A numerical example is presented to demonstrate the feasibility of the proposed design approach.

This paper focuses on problem of quadratic dissipative control for networked nonlinear system with random delay. The T-S discrete fuzzy model system is adopted for modeling the nonlinear system. The dynamic output feedback controller is to be designed. Random delays from the sensor to the controller and from the controller to the actuator are simultaneously considered. And the random delays are described by a binary switching sequence satisfying a Bernoulli distribution. Sufficient conditions for existence of a dynamic output feedback fuzzy controller, such that the closed-loop system is exponentially mean-square stable and strict quadratic dissipative, is present via matrix inequality method. The iterative algorithm is provided to solve the matrix inequalities by using SLPMM (sequentially linear programming matrix method). Finally, a numerical example is given to show the validity and feasibility of the proposed approach.

The problem of the non-fragile dissipative control for the nonlinear discrete systems is dealt with. The T-S models is constructed for nonlinear systems, which makes the model approach to the original system more exact. The sufficient conditions for the existence of a dynamic output feedback fuzzy controller such that, for all admissible multiplicative controller gain variations, the closed-loop system is asymptotically stable and the dissipative performance is guaranteed, are derived in the sense of Lyapunov asymptotic stability and are formulated in the format of matrix inequalities. The sequentially linear programming matrix method (SLPMM) is applied to solve the matrix inequalities. Numerical example is provided to demonstrate the feasibility of the proposed conditions and the procedure of the controllers design.
