Study on satisfactory predictive control algorithm for complex systems

The satisfactory predictive control for complex system is studied. By introducing commanding input and the membership degrees of the predictive output errors between the predictive outputs and their setpoints, the satisfactory predictive control algorithm is improved. Using the satisfactory control algorithm presented in this paper, it cannot only avoid the solving of Diophantine equation for calculating the predictive output, but also deal with the setpoint control problem and horizon control problem, while the hard constraints are guaranteed, the soft constraints and the output tracking are satisfied as much as possible. The simulation results verify the validity.
