Abstract

Focusing on the throttle control system of intelligent vehicle

a model reference adaptive SN-PID controller is presented. Firstly

we obtain the transfer function of a throttle control system by experimental method and design a NARMAX neural network based on the above model

and then the off-line identification and online prediction are carried out. Secondly

the linear quadratic SN-PID algorithm is improved by using immune fuzzy ideas. A model reference adaptive system based on the prediction model of NARMAX neural network is created and an objective function is defined to evaluate the vehicle longitudinal motion

and then the optimal value of all the adjustable parameters in the above controllers is found by the float genetic algorithm. Finally

a digital simulation is carried out to compare the dynamic performance of improved SN-PID controller with the classical one. Results show that the proposed NARMAX neural network is capable of identifying and predicting the output of throttle control system

and the step response velocity of the proposed SN-PID controllers is remarkably faster than that of immune fuzzy and classical ones.
