| 摘 要： | 本论文研究了一种新型预测控制器RTD-A的分数阶实现方法及应用. 与常规控制器比较, RTD-A控制器具有参数意义明确, 易于整定和实施的优点. 论文将RTD-A控制器扩展到分数阶形式, 并与经Z-N法整定的分数阶PI?D1控制器和Wang-Juang-Chan法整定的PID控制器进行了比较. 所提出的分数阶预测控制器在设定值跟踪, 克服负荷扰动, 鲁棒性等方面都有较理想的控制性能. 仿真结果验证了这种分数阶预测控制器的有效性.

| Abstract: | The implementation and application of a new fractional order RTD-A(robustness, tracking, disturbance rejection-overall aggressiveness) controller are studied. Compared to the conventional PID controller, main advantages of the RTD-A controller are its transparent parameters, convenient adjustment and implementation. The RTD-A controller is extended to its fractional form and compared with fractional PI?D1 controller tuned by Z-N method and PID controller tuned byWang-Juang-Chan method. Proposed fractional predictive controller shows good performances in set-point
tracking, disturbance rejection and robustness. Simulation results show the validity of the proposed method. |
