摘要
永磁同步内燃机车电力牵引控制系统中,电流环PI控制对交流信号跟踪能力较差,且前馈解耦项过于依赖电机参数的不变性,因此在介绍原内燃机车牵引控制系统控制策略的基础上,对一种近年来在逆变电源控制中有着广泛应用的比例谐振控制器加以分析与改进。在内燃机车的牵引控制系统中,以改进的准PR控制器代替了原有的PI控制器与前馈解耦项,并通过建模与仿真证明了新的控制器在原牵引控制系统中的可行性。
In the permanent magnet synchronous diesel locomotive electric traction control system,the current loop PI control has poor tracking ability for AC signals,and the feedforward decoupling term is too dependent on the invariance of the motor parameters,so this article introduces the control strategy of the original diesel locomotive traction control system On the basis of this,a proportional resonance controller that has been widely used in inverter power supply control in recent years has been proposed for analysis and improvement.In the traction control system of diesel locomotives,an improved quasi-PR controller has been replaced The original PI controller was decoupled from the feedforward,and the feasibility of the new controller in the original traction control system was proved by modeling and simulation.
