Problems solved by technology

[0002] The theory of PID control is very strong. If there is no experimental device for experiments, it is difficult for students to fully understand the method and principle of PID control. However, the existing teaching methods, for example, control solid-state relays to heat electric heating plates through PID control methods, and The simulation method of the PID adjustment process using thermocouples or thermal resistances as feedback elements, because the resistance wire is easy to burn, and requires 220V voltage, the risk factor is large, and it is not easy to implement, which seriously affects the effect of PID control teaching.

Abstract

The invention discloses a teaching device for simulating PID control and a use method. The device comprises a balance lever, a state feedback device and a PID controller. A disturbance device is arranged at one end of the balance lever, a disturbance balancing device is disposed at the other end of the balance lever, and the balance lever serves as a balance state observation device. Disturbance is applied through the disturbance device at one end of the balance lever; influences generated by disturbance are fed back through the state feedback device; the disturbance balancing device at the other end of the balance lever is adjusted by the PID controller to balance disturbance, so that the balance lever restores the balance state, and a simulation experiment for PID control is achieved; the teaching device is simple in structure, convenient to use, safe and reliable.
