Abstract

Aimed at a multi-channel loading system, a fuzzy model based predictive control with multi-step linearization scheme is proposed. Using a Takagi-Sugeno fuzzy model as a predictive model of the loading system, a linearized fuzzy model with multi-step, the predictive control is applied to the loading system. The result of tests show that this scheme can effectively overcome the unknown influence of nonlinearities and turbulence, it has high control precision and robustness, and other unknown systems can use it for reference.
