双闭环直流调速系统优选设计

OPTIMUM DESIGN ON DOUBLE CLOSE LOOP D.C SPEED GOVERNING SYSTEM

根据自动控制原理和内模控制原理 ,针对双闭环直流调速系统的速度调节器进行设计 ,通过比较选取最优设计方法 ,最优设计的调节器具有PID结构 ,但只有一个可调参数 ,而且这一被调参数与系统的性能直接相关。理论分析和仿真结果表明 ,该调节器能使系统获得优良的动态和静态性能 ,设计方法简单 ,参数调整方便。

Throgh trial-and-error the optimum design plan has been determined in accordance with the principles of automation control and inner analogue control and in light of the design feature of the speed governor of the double close loop D.C speed governing system, the optimally designed governor is in PID structure and it has only one adjustable parameter which has a direct bearing on the performance of the system.Theoretical analysis and emulation results show that the governor helps the system to acquire excellent dynamic and static performance.It is simple and convenient to design and adjust.
