The application study of intelligent PID algorithm for the internal combustion engine control system

In practice, the intelligent PID control algorithm which is an improved algorithm based on the classical PID control was put forward by many researchers to resolve some control problems, such as time-delay, lag and nonlinear. In this paper, an intelligent PID control algorithm is considered and applied to an internal combustion control system. Then, the semi-physical simulation platform based on PLC (Programmable Logic Controller) is set up, where the internal combustion engine is simulated by using simulation model and the intelligent PID controller is realized by using PLC. The results show that the designed control system is stable, and high accuracy and short response time are obtained. Also, the results show the advantage of the presented intelligent PID control algorithm comparing with the classical PID control algorithm.
