基于半实物仿真技术的分数阶PID控制器

The Design of Fractional-order PID Controller Based on Hardware-in-the-loop Simulation

采用半实物仿真技术获得被控对象特性,进而得出系统传递函数。在此基础之上采用分数阶控制器的设计算法设计系统的分数阶控制器。并将该控制器与经典PID控制器进行仿真对比,结果表明:分数阶PID控制器较传统PID控制器,在对系统响应时间的调节上取得了较好的效果。

Making use of hardware-in-the-loop technology,both characteristics of the controlled object and the system transfer function were obtained,and then,a design algorithm of fractional order PID（FOPID） controller was designed.Having it compared with classical PID controller（IOPID） shows that the FOPID outperforms classical PID controller while regulating the system responding time.
