摘　　要：常规静止无功率补偿控制算法存在电力机车限定稳态预测上存在缺点,提出一种改进的限定稳态预测误差电力机车轮动系统无功率补偿控制模型,在常规的静止无功率补偿基础上加一个跟踪误差的积分项,限定稳态预测误差,补偿轮动系统模型的不确定性。设计限定初始状态非线性取代积分控制律,克服常规控制模型在到达阶段不具有鲁棒性的不足。仿真结果表明,改进的限定稳态预测误差电力机车轮动控制模型有较好的削弱稳态误差和抑制抖振特性,机车摇摆幅度较小,能有效控制电力机车的姿态平衡,相比传统方法具有较明显的优越性能,在电力机车智能控制设计领域具有很好的应用前景。The traditional static no power compensation control algorithm had steady-state error, according to the weakness, an improved limited steady-state prediction error static no power compensation control algorithm for electric locomotive wheel system was proposed. Limitation of initial state nonlinear replace the integral control rule was designed, and the con-trol model in the reaching phase was robust. Simulation results show that it can control the attitude balance of electric loco-motive effectively. It has obvious superiority and has good application value in electric locomotive intelligent control design field.
