Abstract :

In this paper, linear model of vehicle suspension accomplished by PID controller has been used to train the ANFIS system, which is instructed online using the PID controller output error and following the training, the PID controller leaves the loop and then the Adaptive Neural – Fuzzy inference system (ANFIS) takes the responsibility of controlling the system by itself. In case of the alteration of the controlled system parameters, the controller will be re-entered the loop and the network will be re-trained using the new error.An important feature of this technique is that it does not require mathematical model of system components such as actuator, spring, shock absorber, all of which are nonlinear; Jacobian system is not required as well. Finally the functional outputs of the controller (ANFIS) which is trained with the usage of a PID controller is compared with a pure proportional-derivative controller. The results show that the controller has been well designed to meet the wished objectives.
