Fault Detection for a Class of impulsive switched systems

International Journal of Automation and computing 2014年第2期11卷 223-230页

作者： Qing-Yu Su Yan-Cheng Li Xing-Ze Dai Jian Li School of Automation Engineering Northeast Dianli University

The problem of fault detection for a class of nonlinear impulsive switched systems is investigated in this paper. Fault detection filters are designed such that the augmented systems are stable, and the residual error signal generated by the filters guarantees the H∞ performance for disturbances and faults. Sufficient conditions for the design of fault detection(FD) filters are presented by linear matrix inequalities. Moreover, the filter gains are characterized according to a solution of a convex optimization. Finally, an example derived from a pulse-width-modulation-driven boost converter is given to illustrate the effectiveness of the FD design approach.

Optimal switch-time control is the study that investigates how best to switch between different modes. In this paper,we solve an optimal switch-time control problem for a class of impulsive switched systems based on observer design. The considered system undergoes jumps at the switching times and the state is only partially known through the outputs. The control variables consist of the impulse times and a set of scalars which determine the jump amplitudes. We present a method that both guarantees that the current control variables remain optimal as the state estimates evolve, and that can be applied to real-time applications. Moreover, the optimal impulsive control strategy can be found using some numerical gradient descent ***, the viability of the proposed method is illustrated through a numerical example.

In this paper, an optimal control problem is solved for a class of impulsive switched autonomous systems. The sequence of active subsystems is pre-specified, and the control variables consist of the impulse times and a set of scalars which determine the jump amplitudes. The subsystems do not require a refractory period, which can bring more generality. Based on the calculus of variation, the partial derivatives of the cost with respect to the control variables are derived, based on which the optimality conditions are given. Finally, two examples are given to testify the viability.
