电牵引采煤机模糊控制系统调速特性的仿真

Simulation of speed regulation characteristic for electrical haulage shearer fuzzy control system

针对采煤机控制存在的时变、非线性、不确定等特点,将模糊控制策略应用到电牵引采煤机调速系统中.仿真结果表明:模糊控制器和传统控制器相比,可使采煤机调速系统响应快、超调小,性能稳定可靠,并对模型参数不依赖,具有较强的鲁棒性.

Fuzzy control was applied to speed regulation system of electrical haulage shearer directed at the characteristics of time-varying, nonlinear and uncertainty. The simulation result indicates that the fuzzy controller makes the speed regulation system of shearer response quickly, small overmodulation, reliable performance and no dependence of model parameter, has strong robustness comparing to traditional controller.
