再生制动在大功率相位摩擦焊中的应用

摘要

针对大功率摩擦焊机定位速度快、精度高的要求，从转子切割定子磁场产生制动电动势出发，分析再生制动的原理和过程，采用再生制动控制技术经过相位调制来实现相位控制。利用Matlab对相位角控制模拟，通过设定边界条件来对相位角进行仿真分析。改变部分参数来对相位角度模拟控制，并对主要参数的模拟结果分析，使摩擦焊接工件的相位误差小于±1°，满足使用要求。实验结果验证了理论分析的可行性和正确性。%Aiming in view of the high power positioning speed high precision requirements of friction weld-er,Starting from the cutting of the stator magnetic field produce brake rotor electromotive force,Analysis principle and process of regenerative braking and regenerative braking control technology after phase modula-tion is used to realize phase control,Using Matlab to the phase Angle control simulation, simulation analysis was carried out on the phase Angle by setting boundary condition,Change some parameters to analog control of phase Angle,And the main parameters of the simulation results analysis, phase error is less than the fric-tion welding tomeet the use requirements, Experimental results verify the correctness and feasibility of the theoretical analysis.
