Abstract: Aiming at the problem of low stability and poor tracking performance of traditional shearer drum heightening technology, a control strategy of shearer drum heightening based on improved simulated annealing algorithm is proposed. Using the improved simulated annealing algorithm and taking ITAE as the performance index of the heightening system, the PID control parameters of the shearer heightening system are optimized. The simulation model of the control system is established by the Simulink toolbox of MATLAB. The control strategy has better robustness and signal tracking ability, which can provide a basis for the efficient production of coal.
