Construction method for intelligent dynamic anti-interference controller of new energy automobile driving motor

Abstract

The invention discloses a construction method for an intelligent dynamic anti-interference controller of a new energy automobile driving motor. The construction method comprises the following steps: collecting an actual current and a reference current of a d-q axis, and establishing a driving motor system 18 through internal module calculation and coordinate transformation; building a driving motor system dynamics model; establishing a torque calculation controller 31, estimating an angle error of the driving motor system dynamics model through the torque calculation controller 31, and introducing a nonlinear disturbance observer 32 to identify uncertain disturbance; establishing a dynamic surface controller; and coping with dynamic uncertainty and uncertain disturbance by adopting recursive wavelet Elman neural network control, and constructing a robust controller for control. Compared with the prior art, the cost is relatively low, the feasibility is relatively high, and the anti-interference performance is relatively good; and the method is easy to implement in engineering.

Description

technical field [0001] The invention belongs to the field of drive of new energy vehicles, and relates to an induction motor control method based on a dynamic surface controller, which is suitable for anti-interference control of drive motors of new energy vehicles. Background technique [0002] In recent years, the substantial consumption of petroleum resources has led to a sharp increase in global energy pressure, and various environmental protection measures are also imminent. The emergence of new energy vehicles has greatly reduced energy consumption and environmental pollution. As one of the three electric vehicles of new energy vehicles, electronic control accounts for a large proportion in the research of new energy vehicles. [0003] Induction motors have the advantages of high reliability, strong robustness, and low cost. Moreover, they are easy to achieve higher speeds, lower manufacturing costs, and have a wider range of speed control. They can be used in electric...
