CHATTERING REMOVAL DEVICE OF VARIABLE STRUCTURE CONTROL SYSTEMS

摘要

The present invention relates to a chattering removal device of a variable structure control system. In the conventional variable structure control system, since a nonlinear control input signal (U _N ) applied to the system is essentially a discontinuous function, it becomes a high frequency control input to the system. There was a problem that the ring phenomenon occurs. The present invention eliminates the chattering phenomenon by replacing the conventional nonlinear control input signal (U _N ) with a linear control input signal (U _L ), which is a continuous function of low frequency components, to solve the above problems. There is.
