本文研究了一个新柱型电动力转向(EPS-TT)系统。这种EPS-TT系统的显著特点是采用光隔离转矩传感器测量转向器转矩,它的辅助转矩控制方法是采用一个单向马达和两个离合器。因而它不需要一个复杂的马达驱动系统,该系统在作反向转动时要耗费大量的电能。为估算EPS-TT开发了一个完整的转向系统模型和一个简化了的模型。一个完整的车辆模型用来研究车辆的响应。为控制EPS-TT系统设计了线圈载体控制法和比例积分微分控制算法。分析了加于系列不同正弦输入和结果性能。结果表明用ESP-TT系统所达到的性能和常规的ESP系统通过的频率范围相似。整个转向系统模型结果和简化了的模型结果相似但车辆的响应稍稍不同。该线圈载体控制提供了好的性能不影响车辆的稳定性和可控性。
This article studies a new column type electric power steering (EPS-TT) system. Notable feature of this EPS-TT system is the use of optically isolated torque sensor to measure the steering torque, and its auxiliary torque control method is the use of a one-way motor and two clutches. It therefore does not require a complicated motor drive system, which consumes a lot of power when it is turned in reverse. A complete steering system model and a simplified model were developed for estimating EPS-TT. A complete vehicle model is used to study the vehicle’s response. In order to control the EPS-TT system, the coil carrier control method and the proportional-integral-derivative control algorithm are designed. Analysis of the series added to the different sinusoidal input and the resulting performance. The results show that the performance achieved with the ESP-TT system is similar to that of a conventional ESP system. The overall steering system model results are similar to the simplified model but the vehicle response is slightly different. The coil carrier control provides good performance without affecting the stability and controllability of the vehicle.
