Description

technical field [0001] The invention relates to electric power-assisted bicycle technology, in particular to an adaptive control system for a brushless DC motor. Background technique [0002] Due to the convenience of use, electric assist bicycles are more and more used in people's lives. At present, power-assisted bicycles in the industry are mainly mechatronic personal vehicles that use batteries as auxiliary energy sources on the basis of ordinary bicycles, and are equipped with hub motors, controllers, batteries, torque speed sensors and display instrument systems. At present, the driving motors of power-assisted bicycles are mainly divided into front hub motors and rear hub motors. Based on the advantages of convenient riding, they are being used by more and more people, especially in high-end power-assisted bicycles. The controller is usually set separately from the driving motor, and the controller is connected to the motor lead wire of the driving motor, the power l...
