| 英文摘要 |
| The preferred features for a nonlinear PID controller are its simplicity and effectiveness. To achieve these features, we propose a new class of nonlinear PID controller, analyze the nonlinear function characteristics and develop the method of parameter selection. Firstly, we put forward a method for constructing nonlinear functions based on the action principle of the electric field between two plates of a capacitor. This method is applied to modify the conventional PID controller to form a new class of nonlinear PID controller. Secondly, an analysis is given to the nonlinear function, revealing the relation between the function and its parameter. Thirdly, concepts of T-Passivity are employed to explore the stability of the nonlinear PID controller, and a guideline for the parameter selection of the nonlinear controller is given. Simulation shows the validities of the nonlinear PID controller and its parameter selection conclusion. |
