摘要

将变结构系统(VSS)与李亚普诺夫设计相结合，提出了一种新的离散控制算法。它既具有滑模控制的所有优良特性，又避免了控制输入不必要的不连续，从而消除了颤振，而颤振一直被认为是VSS应用的严重障碍。提出了一种基于离散时间滑模的定子电流和转矩统一控制方法，并将其应用于IM驱动器的间接矢量控制。由于被广泛使用的PWM技术取代了迟滞控制器，滑模方法可以应用于IM伺服驱动器的控制。所有的理论问题都得到了实验的验证。实验系统由单片机和T805组成，实现了并行处理。

Robust chattering free sliding mode control of servo drives

A new discrete-time control algorithm has been developed by combining variable structure systems (VSS) and Lyapunov design. It possesses all the good properties of the sliding mode control and avoids the unnecessary discontinuity of the control input, thus eliminating chattering which has been considered as a serious obstacle for applications of VSS. A unified control approach for the stator currents and torque control based on the discrete-time sliding mode for application in indirect vector control of an IM drive is developed. The sliding mode approach can be applied to the control of an IM servodrive due to the replacement of the hysteresis controller with the widely used PWM technique. All the theoretical issues are verified by experiments. The experimental system consists of a transputer T805 and a microcontroller, which enables parallel processing.<>
