Abstract:

A new method of model reference variable structure control with sliding mode (MRVSCSM) is proposed for a class of time varying linear system. This method employs the time varying reference model and time varying switch function to adapt the largely change of system parameters, and to improve efficiency and accuracy of control. This method is applied to design control laws of Pitch/Yaw channels autopilot for BTT missiles. The digital simulation shows that the system has good performance and robustness.

Key words: time-varying linear system, time-varying sliding mode, model reference variable structure controller
