Design and Simulation of DC Motor Controller Based on Modern Control Theory

主要介绍的是运用现代控制理论对直流电机的转速控制系统进行设计与仿真,运用MATLAB/Simulink仿真使直流电机的转速达到预期的动态性能要求和稳态要求(最大超调量σ<5%;调整时间ts<0.5 s;稳态误差为0),相对于传统PID算法,基于现代控制的算法可降低计算量,使用廉价处理器降低成本。

Mainly introducing the application of modern control theory of DC motor speed control system design and simulation, using MATLAB/Simulink simulation to DC motor speed to meet the requirements of the desired dynamic performance and steady-state requirements （maximum overshoot adjustment time of σ〈5%; ts〈0.5 s; steady state error 0）compared with the traditional PID algorithm, control algorithm of modem control it can reduce calculation based on the use of cheap processors to reduce costs.
