Abstract

The invention discloses a hybrid electric vehicle belt-driven started generator (BSG) torque ripple compensating controller and a construction method of the hybrid electric vehicle BSG torque ripple compensating controller. The torque ripple compensating controller controls a composite controlled object. The torque ripple compensating controller comprises a PI adjuster, an extended inverter control module and a current compensating module. The composite controlled object comprises a hybrid electric vehicle BSG, a photoelectrical coded disk and a revolving speed and electrical degree calculation module. A neural network is adopted to build the current compensating module, the neural network is of a four-layer structure, and the neural network is trained by the adoption of the Powell algorithm. According to the hybrid electric vehicle BSG torque ripple compensating controller and the construction method of the hybrid electric vehicle BSG torque ripple compensating controller, the current compensating module is recognized through the neural network, the current harmonic wave of a BSG motor can be restrained effectively, and the torque ripple of the motor is reduced significantly, so that the hybrid electric vehicle BSG system has good dynamic and static characteristics and very strong robustness.

Description

technical field [0001] The invention relates to a torque fluctuation compensation controller of a hybrid electric vehicle belt-driven starter generator (hereinafter referred to as BSG) system and a construction method thereof, which is suitable for effective compensation of torque fluctuations of a hybrid electric vehicle BSG system and belongs to the technical field of BSG hybrid power . Background technique [0002] At present, in the "2013 China Motor Vehicle Pollution Prevention and Control Annual Report" issued by relevant departments, the national motor vehicle pollution emissions in 2013 have been announced. Motor vehicle pollution is an important cause of photochemical smog pollution and haze, and has become one of the important sources of air pollution in my country. Therefore, the urgency of motor vehicle pollution prevention and control has become increasingly prominent. Especially in the "Energy-saving and New Energy Automobile Industry Development Plan (2012-20...
