Abstract

The invention discloses a construction method of a robust optimal anti-interference controller of a new energy automobile driving motor. The method comprises the steps of firstly, establishing a driving motor system, and then sequentially establishing an error observer, a backstepping controller, an optimal controller, a self-constructed neural network controller, a robust controller and an adaptive controller to form robust optimal anti-interference controller of the driving motor. According to the invention, the defects of the existing control method of the new energy automobile driving motor are effectively solved, the design is simple, the control effect is excellent, and the anti-interference capability is very strong. The controller only needs to be programmed on software, hardware equipment does not need to be added, that is, an actual controller on the physical layer does not need to be added. Compared with the prior art, the construction method is low in cost, high in feasibility, good in anti-interference performance and easy to implement in engineering.

Description

technical field [0001] The invention belongs to the field of driving of new energy vehicles, and relates to a driving motor control method based on a robust optimal anti-jamming controller, which is suitable for the anti-jamming control of driving 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] Compared with synchronous motors and asynchronous motors, permanent magnet synchronous motors have no electrical excitation and corresponding losses, permanent magnet rotors do not heat up, and the electrical load can be sele...
