摘要
提出了一种分数阶控制器的设计方法,首先对S传递函数进行相应的Z变换,然后根据最短记忆法[1]用Grünwald Letnicov分数导数定义取其近似项,来完成分数阶控制器的设计.仿真结果证明这种方法是可行有效性的.
A method of design of fractional order controller was given. At first Z - transform fitting s - transfer function is taken and then some limited terms of the definition of Grünwald- Letnico fractional calculus are used by short memory principle,at last the design of fractional order PID controller can be completed. And the simulation outcomes verify the effectiveness of the method proposed.
