基于改进OOA PID控制器的有机固废裂解釜温度控制

PID Control of Organic Solid Waste Cracking Kettle Temperature Based on Osprey Optimization Algorithm

为了突破传统PID控制器在有机固废裂解系统中无法有效处理非线性系统、缺乏全局优化等局限性,提出了基于改进鱼鹰优化算法(OOA)的PID控制器。首先,对裂解釜温度系统传递函数模型的参数进行辨识;然后,运用改进OOA算法优化PID控制器参数;最后,通过MATLAB/Simulink进行仿真实验。仿真结果表明,改进后OOA PID控制器相较传统的OOA PID控制器控制效果提升显著,超调量减小了2.6%,系统动态响应时间缩短了约42%。

In order to break through the limitations of traditional PID controller in the thermal cracking system of organic solid waste,such as the inability to effectively deal with the nonlinear system and the lack of global optimisation,the PID controller with the improved Osprey Optimization Algorithm(OOA)is proposed.Firstly,the parameters of the transfer function model of the cracking kettle temperature system are identified by the step reaction two-point method;then,the improved OOA algorithm is applied to optimise the PID controller parameters.The simulation results by MATLAB/Simulink show that the control effect of the improved OOA PID controller is significantly improved comparing with the traditional OOA PID controller,the overshooting amount is reduced by 2.6%,and the dynamic response time of the system is shortened by about 42%.
