State feedback predictive control for hybrid system via parametric optimization
Li, XG; Huang, DX; Gao, DJ
AbstractIn this article, state feedback predictive controller for hybrid system via parametric programming is proposed. First, mixed logic dynamic (MLD) modeling mechanism for hybrid system is analyzed, which has a distinguished advantage to deal with the logic rules and constraints of a plant. Model predictive control algorithm with moving horizon state estimator (MHE) is presented. The estimator is adopted to estimate the current state of the plant with process disturbance and measurement noise, and the state estimated are utilized in the predictive controller for both regulation and tracking problems of the hybrid system based on MLD model. Off-line parametric programming is adopted and then on-line mixed integer programming problem can be treated as the parameter programming with estimated state as the parameters. A three tank system is used for computer simulation, results show that the proposed MHE based predictive control via parametric programming is effective for hybrid system with model/plant mismatch, and has a potential for the engineering applications.
