Mine Hoist Speed Controller Design Based on L_1 Adaptive Control Theory

Luo Qingshun;Li Jinglan;Liu Hui;Yang Qinmin;Zhejiang University;Tiandi Science & Technology Co.,Ltd.;  
A mine hoist system dynamic model was firstly analyzed.According to the characteristics of time-variation,nonlinearity,strong coupling,great inertia,unknown load within the system dynamics,a newL_1 adaptive controller was adopted to online learn the operating conditions,to adjust the controller parameters in real time,and well control effectiveness in the global environment was obtained.L_1 controller was proved to have arbitrary steady states and transient tracking precision when the adaptive gain was chosen large enough through strict mathematical verification.Then the feasibility of L_1 controller was validated in MATLAB simulation environment and a test was conducted in real mechanical platform.The results show that the mine hoist control system may still track the given speed curve along with satisfactory tracking accuracy and robustness when the load is unknown.
