【摘要】 在传统串级控制基础上结合分数阶PI~λD~μ控制器,提出过热汽温的分数阶PI~λD~μ串级控制策略。采用粒子群优化算法对分数阶PI~λD~μ控制器参数进行整定。在Matlab/Simulink仿真环境中对分数阶PI~λD~μ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PI~λD~μ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。更多还原

【Abstract】 Basing on the traditional cascade control and fractional order PI~λD~μcontroller,a fractional order PI~λD~μcascade control strategy for superheated steam temperature control was proposed and the fractional order PI~λD~μcontroller parameters were set with particle swarm optimization algorithm.Simulation in Matlab/Simulink and comparing fractional order PI~λD~μcontroller with integer order PID controller show that the former outperforms the latter in setting value tracking,disturbance control and robustness.更多还原
