Therefore, the core problem of the controller is how to select the proportion, integral, derivative, these parameters are difficult to adjust, so the application of PID controller is limited. In fact, the PID control law is a linear control law. In addition, the existing control theory also has its weakness. The simple linear single variable system has high control effect, while the complex system has no effect.
