Performance Analysis of Model Free Control Method

Model-free control method is discussed,which has received good results in the practical application because of excellent performance,such as adaptability,anti-jamming capability,decoupling performance,mandatory stability,etc.To the necessity and difficulty of the theory analysis of these performances,the simulation results of some important performances of model-free control method are introduced.Because more than 90 percents of controllers used in industrial process control are PID regulators,the simulation is done to compare the corresponding performances of PID regulators.Simulation results show that the model-free control method is better than PID regulator in adaptability,anti-jamming capability,decoupling performance,mandatory stability.The designed simulation system is simply introduced.
