基于CMAC-PID控制的柴油发电机组的建模与仿真

Modeling and Evaluating of Diesel Generators Based on CMAC-PID

在分析柴油发电机组系统组成的基础上,建立了火电厂应急柴油发电机组在MATLAB/SIMULINK环境下的仿真模型,提出了应急柴油发电机组调速系统的CMAC-PID控制方案。对顺序投入负载时,机组的机械、电气性能作了仿真分析,结果表明CMAC-PID控制的应急柴油发电机组,转速瞬态调整率要比常规PID控制下小,稳定时间也短,显示了良好的动态特性。

Computer models were developed under the environment of MATLAB/SIMULINK and the CMAC-PID control scheme of emergency diesel generators in heat-engine plant was presented too. Mechanical and electrical performance were simulated and analyzed while the loads were increased orderly. The simulation results illustrate that emergency diesel generators controlled under CMAC neural network combined with PID is better in dynamic characteristics than the conventional PID controller in the speed transient adjustment rate and stabilization time.
