直流伺服电机用MATLAB实现的源代码，伺服系统由具有位置反馈、速度反馈和电流反馈的三闭环结构组成本控制系统采用模糊和PID复合控制，在小偏差时转化为P ID控制，这样就获得了比纯模糊控制更高的稳态精度，有比P ID控制更快的动态响应、更小的超调量。(DC servo motor to achieve with the MATLAB source code, by a position feedback servo system, the speed feedback and current feedback loop structure composed of three of the control system using fuzzy and PID compound control, in a small deviation into the P ID control, so that access to higher than the pure fuzzy control steady-state accuracy, faster than P ID control the dynamic response, smaller overshoot.)
