在对现有的基于牵引速度调整的恒功率控制系统在应用中出现的控制效率低下、可控性差的缺点分析的基础上,提出了新的基于磁流变触觉反馈的采煤机恒功率控制系统方案,对该控制系统的结构特征及工作原理进行了深入的分析,并利用MATLAB/SIMULINK仿真分析软件对该控制系统的控制进行了仿真分析。分析结果表明:磁流变阻可以根据电流可以实现对阻尼力的连续控制,完全满足对采煤机工作中快速、精确、连续的恒功率控制要求,极大的提升了采煤机工作时的稳定性和工作效率。

Based on the analysis of the disadvantages of low control efficiency and poor controllability of the existing constant power control system based on traction speed adjustment, a new scheme of constant power control system for shearer based on magneto-rheological tactile feedback is proposed. The structure characteristics and working principle of the control system are analyzed deeply, and the control of the control system is simulated and analyzed by using the MATLAB/SIMULINK simulation analysis software. The results show that the magnetorheological resistance can be controlled continuously according to the current, which can satisfy the requirement of fast, accurate and continuous constant power control in the work of shearer to greatly improve the shearer working stability and efficiency.
