该系统基于MAX1978和TEC的工作原理，采用多点不同频率的测量方法，并建立了相应的数学模型。根据数学模型的幅频特性和相频特性，确定了控制器的零极点图，然后调整相应的电路电阻和电容，使温度调节精度达到1E-3℃。
The system based on the working principle of MAX1978 and TEC, using multi-point at different frequency measurement method, and establishing corresponding mathematical model. Confirmed the pole-zero plot of the PID, according to the amplitude-frequency and phase-frequency characteristics of the mathematical model, and then, adjusted the corresponding resistance and capacitance of the circuit to make the accuracy of the temperature adjustment to 1E-3centigrade.
