Tms320lf2407dsp Diesel Engine Speed-based Intelligent Pid Control System

Process control systems use PID controller extensively. The PID controller has many good characteristics such as simple structure, good adaptability, and it has a long period application. Control engineer had accumulated many experiences in PID controller parameter regulation. But because shipping power system is rather complex system, which need the ship, the main machine and the propeller to cooperate closely. The rpm control system is a non-linear, time varying system, so it is difficult for the traditional PID controller to reach optimum control result.This article researches the intelligent PID control algorithms carefully. After a particular introduction of single neuron intelligent PID controller and it's parameter self-regulating algorithm, this article realized the following algorithm on TMS320LF2407 DSP with C language: traditional PID control algorithm, single neuron adaptive control algorithm supervised by Hebb learning algorithm and single neuron adaptive control algorithm using Pe2(k + d) + Qu2(k) as performance figure. Emulation result indicates that those methods have satisfactory control result.This article also had a detailed discussion on TMS320LF2407 DSP C language programming. Some programs such as SCI Serial communication module and SVPWM (Space Vector Pulse Width Modulation) module were programmed on a 2407 microcontroller.
