An Improved Model-free Adaptive Predictive Control Algorithm For Nonlinear Systems With Large Time Delay

摘要

For control problem of nonlinear time-delay systems, we improve the control input criteria function of the model-free adaptive control by adding the sum of control output error into the control input criteria function. Also, the concept of predictive control has been incorporated into the improved algorithm. Typical linear and nonlinear large time-delay systems are introduced for simulation comparison tests. The simulation results show that the improved model-free predictive control algorithm can achieve stable output, better control effect and faster response. Thus, the effectiveness of this improved model-free predictive control method is fully illustrated.
