Simulation Research of CVT Variable Fertilization Control System

Abstract:

Using MATLAB to establish emulation model of variable rate fertilization control system, using the Z-N method to setting the system of PID parameters, emulation of the system has without PID controller and PID controller, analysis and evaluation of the system dynamic performance index and steady-state performance index. The emulation results shows that the system with PID controller, the maximum overshoot reduce, adjusting time short, improve the time domain dynamic index; phase margin increase, magnitude increase, improved the performance index of the frequency domain.
