Constant Palstance Control of Combine Cylinder Based On Nonlinear PID

Article Preview

Abstract:

Considering that the threshing cylinder palstance system has characteristics of nonlinear, time-delay, what’s more the control environment is very complex and multi-disturbance; this paper presented the method of nonlinear PID to control the cylinder palstance. Firstly, The paper analyzes characteristics of the model of the threshing cylinder palstance system .Then the nonlinear PID controller is designed, and with the threshing cylinder palstance system constitute a closed-loop control system. Finally, simulation results show the effectiveness and feasibility of the proposed method.
