摘要
为抑制快速反射镜开机温漂,以及实现快速反射镜在设定温度条件下正常工作,设计了温度控制系统与新型控制方案,来实现对快速反射镜温度的精确控制。温控系统以单片机为核心控制元件,热电制冷器为执行元件。设计基于小波去噪的非线性比例-积分-微分自抗扰控制方案,通过基于Sigmoid个性化惯性权重的粒子群优化算法整定控制参数,进行仿真和实验。结果表明,此控制方案能有效抑制快速反射镜的开机温漂,在15~28℃的控温范围内,控温精度达到±0.02℃,可在142 s内稳定在预设温度。所设计的温控系统响应速度快、控制精度高,鲁棒性强,具有较好的应用价值。
The present study aimed to design a temperature control system and a new control scheme to precisely control the temperature of the fast steering mirror.The temperature control system considered the single chip microcomputer as the core control element,and the thermoelectric cooler as the executive element.The system used a nonlinear proportionalintegralderivative active disturbance rejection control algorithm based on wavelet denoising to control the temperature.The control parameters were tuned through particle swarm optimization algorithm based on Sigmoid personalized inertia weight.The simulation and experimental results show the effectiveness of the control scheme in suppressing the startup temperature drift of the fast reflector.It is found that the temperature control accuracy reaches±0.02℃in the temperature control range of 15℃-28℃,which can be stabilized at the preset temperature within 142 s.In addition,the results show that the designed temperature control system has fast response speed,highcontrol accuracy,strong robustness,and good performance of application value.
