分数阶控制器在过热汽温控制中的应用研究

摘要

Basing on the traditional cascade control and fractional order PIλDμ controller, a fractional order PIλDμ cascade control strategy for superheated steam temperature control was proposed and the fractional order PIλDμ controller parameters were set with particle swarm optimization algorithm. Simulation in Matlab/Simulink and comparing fractional order PIλDμ controller with integer order PID controller show that the former outperforms the latter in setting value tracking,disturbance control and robustness.%在传统串级控制基础上结合分数阶PIλ Dμ控制器,提出过热汽温的分数阶PIλDμ串级控制策略.采用粒子群优化算法对分数阶PIλ Dμ控制器参数进行整定.在Matlab/Simulink仿真环境中对分数阶PIλDμ控制器和整数阶PID控制器的控制效果进行仿真对比,结果表明分数阶pIλ Dμ控制器在设定值跟踪、扰动抑制和鲁棒性方面优于整数阶PID控制器.
