Abstract

The invention discloses a torque fluctuation compensation controller for a hybrid vehicle belt-type drive starter generator (hereinafter referred to as BSG) and a construction method thereof. The torque fluctuation compensation controller controls the compound controlled object, and the rotating The torque fluctuation compensation controller includes a PI regulator, an extended inverter control module and a current compensation module, and the composite controlled object includes a hybrid electric vehicle BSG, a photoelectric encoder disc, and a calculation module for rotational speed and electrical angle; the neural network is used to construct The current compensation module, the neural network adopts a four-layer structure, and uses the Powell algorithm to train the neural network. The method of the present invention can effectively suppress the current harmonics of the BSG motor by using the neural network to identify the current compensation module, significantly Reduce the torque ripple of the motor, so that the BSG system of the hybrid electric vehicle has good dynamic and static characteristics and 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...
