提出一种基于比例—积分和相位超前校正的闭环控制器设计,并验证电路在全温状态下的稳定性.分析闭环控制器的工作原理和电路的设计方案,并对闭环控制器的电路进行了仿真,得到了比较理想的结果.证明了在驱动回路和检测回路较小频率差的前提下,可通过控制系统的优化达到拓展带宽的目的.在不同温度状态下检测电路的性能,实验结果显示温度不会影响控制器的稳定性,但会影响控制器的带宽.%A closed loop controller design based on proportional-integral and phase lead correction is proposed,and verify the stability of the circuit in the full temperature state. Analyze the working principle and circuit design of the closed loop controller,simulating the circuit of the closed-loop controller,having got the ideal result. In the condi?tion that the driving circuit and the detection circuit are less frequently,we can achieve the purpose of expanding the bandwidth by controlling the optimization of system. Lastly,detect the performance of circuit at different temper?atures. Experimental results show that the temperature does not affect the stability of the controller ,but it will affect the bandwidth of the controller.
