摘　　要：针对一类线性时变系统，提出了一种时变最终滑态变结构调节器设计方法。该调节器采用时变切换函数，能较好地适应系统参数大范围的变化。数字仿真表明，该调节器具有良好的控制品质和鲁棒性能。It is often possible to identify accurately the parameters of time varying plants; we make use of this information to obtain better control properties of such systems. We propose a new timevarying terminal sliding mode variable structure regulator control law. Our method employs timevarying switch function to improve efficiency and accuracy of control systems. We analyze via Lyapunov stability theory the stability of the variable structure regulator control system designed with our method. Finally, simulation results for an actual plant (Figs.1 and 2) show that the regulator can effectively adapt itself to the very large range of parameter variation of timevarying plant.
