Summary:
Considering that traditional PID controller has the problem for amplifying the noise when extracting the differential of signal, the tracking-differentiator is adopted to construct the nonlinear PID controller. The theoretical analysis and simulation are done to study the influence of the tracking-differentiator to the control process. Then the designed nonlinear PID controller is adopted into the controlling part of the DC-DC converter to optimize the dynamic property. A boost converter is taken as an example, compared with traditional PID controller, the simulation shows that the nonlinear PID controller can control the system more quickly and smoothly.
