Abstract:The embedded drive control system of the hub motor constitutes of two closed-loop of current and speed controllers. The motor drive circuit, the speed detection circuit, the current detection circuit, and the overcurrent overload protection circuit are designed. The fuzzy adaptive proportion integration differentiation (PID) control algorithm is used to simulate the electric wheel type trolley on the dynamometer platform. The test results show that the trolley is stable and can be operated at different speeds under different load conditions. The protection system is triggered in the case of overcurrent or overload, which prevents the current from being burned out and burns the hardware circuit. The driving control system is safe, reliable and stable, which can provide reference for the analysis and verification of the stability of the electric wheel drive control system.
