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 chos...
