摘要
为了研究电力机车受电弓抬升高度的控制精度,考虑机车车体振动对受电弓的扰动,建立了机车受电弓三元集总质量归算数学模型;依据Lyapunov稳定性理论,构造了静抬升力多滑模鲁棒控制器,并采用引入混沌变异因子的万有引力算法对控制器参数进行寻优。理论分析及仿真结果表明,在面对复杂的车体振动激扰时,机车受电弓抬升高度跟踪误差一致有界,对输入指令具有较好的跟踪效果。
For the study of control accuracy of pantograph elevation on electric locomotive,a mathematical model of pantograph ternary lumped mass reduction is established after considering excitation of pantograph by locomotive body vibration.According to the Lyapunov stability theory,a multi-sliding mode robust controller for static lift force is constructed with its parameters optimized by chaosg SA.Theoretical analyses and simulation results demonstrate that the tracking error of pantograph elevation of locomotive is uniformly bounded of complex vehicle body vibration excitation with better tracking performance to input command.
