摘要: 基于开关型霍尔位置传感器的永磁同步电动机控制系统虽具有高功率密度、高效率等优势,但该类型传感器的信号跳变离散,使电动机的位置和速度估算出现较大误差,进而影响了储纬器纱线输送的运行性能。为提高电动机转子估算的精度,以增强储纬器纱线输送的稳定性,提出了基于卡尔曼前馈拟合状态观测器的电动机转子位置和速度估计方法。首先采用卡尔曼迭代算法对离散的霍尔信号进行滤波及拟合,以消除霍尔安装偏差造成的噪声扰动;其次,采用全维状态观测器对电动机的转子位置信息进行估算,最终获得连续的电动机转子位置和速度信息。为验证提出算法的有效性,搭建实验平台进行了测试。结果表明:相较于传统的线性外插算法,采用改进卡尔曼前馈拟合状态观测器算法的系统,在启动阶段,电动机转子位置及速度的估算精度更高;在整个运行过程,纱线输送的动态性能和稳态性能更好。

Abstract:

Objective In order to meet the high-speed and high stability control requirements of the motor driving sulutions for the application of weft storage, and to improve the accuracy of position and speed estimation in the permanent magnet synchronous motor drive system based on Hall sensors so as to enhance the stability of yarn transport in the weft storage device, This paper analyzes in detail the working principle of Hall sensors and proposes a motor rotor position and speed estimation method based on Kalman feedforward fitting state observer to address the problems of discrete position signals and low speed estimation accuracy in the permanent magnet synchronous motor drive system based on Hall sensors.

Method This article provides a detailed analysis of the working principle of Hall sensors and proposes a motor rotor position and velocity estimation method based on Kalman feedforward fitting state observer. First of all, This method uses the Kalman iterative algorithm to filter and fit the discrete Hall signal, eliminating the noise disturbance caused by Hall installation deviation; secondly, a full dimensional state observer is adopted to estimate the rotor position information of the motor, ultimately obtaining continuous rotor position and velocity information of the motor.

Results Compared with conventional algorithms, in the motor drive performance testing section, using the algorithm proposed, running at a given speed of 500 r/min, the startup response time is consistent and the steady-state error is reduced by 15%. At a given speed of 1 500 r/min, the startup time was shortened by 0.2 s and the steady-state error was reduced by 11.5%. At a given speed of 5 000 r/min, the startup time was shortened by 0.8 s and the steady-state error was reduced by 0.8%. In the performance testing of closed-loop yarn conveying in the weft storage device, the algorithm proposed was a dopted to shorten the start-up time by 0.1 s and steady-state error by 7.6% under the condition of external sock machine pulling yarn speed of 100 m/min. Under the condition of external sock machine pulling yarn at a speed of 700 m/min, the startup time was shortened by 0.2 s and the steady-state error was reduced by 13.3%.

Conclusion The experimental results show that compared with conventional algorithms, the proposed energy storage control system based on Kalman feedforward fitted state observer has higher estimation accuracy of motor rotor position and velocity during start-up and steady-state operation, and better motor driving performance; in the process of yarn conveying, the dynamic and steady-state performance of the weft storage control system is better, which better meets the high-performance control requirements of weft storage yarn conveying.
