PID parameter setting temperature control experiment teaching device and method

The invention discloses a PID parameter setting temperature control experiment teaching device and method, and relates to the field of control engineering. The device comprises a controller with a built-in position type PID control program and an oil tank; the hydraulic pump and the proportional pressure valve are sequentially arranged between the outlet of the oil tank and the inlet of the oil tank in the oil flowing direction; a temperature sensor is arranged in the oil tank; the controller is respectively connected with the temperature sensor and the proportional pressure valve; the controller is used for controlling the proportional pressure valve to work according to the oil liquid temperature collected by the temperature sensor and the position type PID control program so as to heat oil liquid passing through the proportional pressure valve. The device has the advantages of simple structure, uniform heating and the like. 本发明公开了一种PID参数整定温度控制实验教学装置及方法，涉及控制工程领域，该装置包括内置有位置式PID控制程序的控制器以及油箱；在油箱的出口与油箱的入口之间且沿油的
