为实现太阳能电池板接收光照幅度的最大化,提高对光源精确定位等问题,提出借鉴模糊免疫响应原理,将模糊免疫PID控制算法引入太阳能光源定位追踪驱动系统中。通过构建定位追踪驱动系统的传递函数,应用MATLAB/Simulink平台验证所构建控制器的运行性能。仿真结果表明:该控制算法在工况突变和扰动存在时,能有效消除系统误差,获得更高的控制精度和稳定性。

In order to achieve the solar panels light receiving maximum amplitude and improve the light source positioning accurately, the fuzzy immune PID control algorithm is applied to the positioning and track- ing system of solar light source based on the regulation principle of fuzzy immune response. By constructing the transfer function of the positioning and tracking drive system, the operation performance of the controller is verified by the MATLAB/Simulink platform. The simulation results show that the control algorithm can elimi- nate the system error and obtain higher accuracy and stability when the control algorithm is in the condition of mutation and disturbance.
