摘要
复杂函数的计算是高性能全数字化伺服电机控制系统设计中需要考虑的重要问题之一。本文从DSP系统的特点出发,以切比雪夫多项式为基础,提出了一种简便、快速、精确计算复杂函数的方法。在与泰勒展开方法的对比中,显示了该方法的优越性。通过在永磁同步电机无机械传感器控制系统的应用,验证了该方法的可行性。
The calculation of complex functions is an important problem in the design of full-digital servo drives. Based on Chebyshev multinomial, a new algorithm is proposed to process complex functions in this paper. Its benefit is shown in comparison with the method of Taylor series. And its validity is verified in its application in a sensorless control system of PMSM.
