Abstract

An adaptive sliding-mode control algorithm has been developed for a multi-degree-of-freedom microgravity isolation system such that the desired transmissibility matrix is achieved. The reference model corresponds to the desired transmissibility matrix. The control law is based on the sliding mode control theory. Sliding hyperplanes with boundary layers are chosen in the state space consisting of errors between the outputs of the actual system and the reference model and their derivatives. The adaptation mechanism is designed on the basis of a Lyapunov function consisting of tracking errors and parameter errors. Numerical results are presented for a three-degree-of-freedom system. It has been found that the resulting transmissibility matrix is very close to the desired function.
