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PIλDμ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.
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 PIλDμ controller tuned by Z-N method and PID controller tuned by Wang-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.
