A Novel Model Free Adaptive Controller With Tracking Differentiator

An new model-free adaptive controller (MFAC) is proposed, combining the single output TD(tracking differentiator) with the basic MFAC. The novel TD-MFAC method improves the capacity of anti-jamming because of the filter characteristic of the single output tracking differentiator. Furthermore, TD-MFAC method is compared with PID control method. The simulation results show the model-free adaptive control method with tracking differentiator is better than PID control method in tracking, adaptability and overcoming the large time-delay of the system obviously. The proposed method also enhances the anti-jamming ability of model-free adaptive control method.
