Based on Fuzzy Terminal Sliding Mode Variable Structure Control Strategy

摘要

In the general sliding mode control, often choose a hyperplane to make the system reach the sliding mode, the tracking error and gradual decay to zero, and the gradual convergence of the speed by selecting the sliding surface parameter matrix of arbitrary regulation, in spite of the state in any case tracking error will converge to zero in finite time, but also a certain degree of jitter. In order to obtain better performance, this paper presents a fuzz-based Terminal sliding mode variable structure control, that is, the introduction of non-linear function of sliding hyperplane constructed Terminal side, while Terminal by adding fuzzy control regulation,Lyapunov proof and the final adoption of MATLAB-MIMO system simulation, the control strategy obtained has better robustness, stability and good control effect.
