摘要
针对燃烧器温度控制系统是一个时变、大延迟和非线性的控制系统,无法建立准确数学模型,难以进行精确控制的问题,常使用模糊PID算法实现对此类系统的控制。但模糊PID算法需要专家给出模糊规则并调节参数,且参数调节过程中存在误差,控制性能较差。本文采用粒子群优化模糊PID算法中的量化因子Ke、Kec和比例因子Ku,快速整定模糊PID参数,然后利用MATLAB对控制系统进行仿真。结果表明,通过粒子群优化的模糊PID,系统的响应速度更快、超调量更小、达到稳态的时间更短。
Because the temperature control system of burner is a time-varying,large delay and non-linear control system,it is difficult to establish an accurate mathematical model and control temperature accurately.Fuzzy PID algorithm is often used to control this kind of system.But the fuzzy PID algorithm needs experts to give the fuzzy rules and adjust the parameters,and there are errors in the process of parameter adjustment,so the control performance is often poor.In this paper,the quantization factors Ke,Kec and proportional factor Ku in the particle swarm optimization fuzzy PID algorithm are used to rapid setting parameters,and then the control system is simulated with MATLAB.The results show that the response speed of the system is faster,the overshoot is smaller and the time to reach the steady state is shorter with the fuzzy PID optimized than particle swarm optimization.
