【Abstract】 The mathematical model for a temperature control system has been developed.Themethod of setting up the controller parameter is described. The instability of the system andthe nonlinear error in temperature measurement are discussed.Two methods of correctingthe non-linearity are proposed.The temperature measurement error is less than 0.1℃andthe steady-state temperature fluctuation is less than 0.02℃。The system is suitable for usein the precision control of the temperature of photoelectrical devices.更多还原
