The Hybrid RFNN Control for a PMSM Drive Electric Scooter Using Rotor Flux Estimator
Figure 3
Experimental results of PI control system with mounted electric scooter at 1200 rpm: (a) command rotor speed , measure rotor speed , and estimate rotor speed ; (b) measure rotor position and estimate rotor position ; (c) command current and measure current in phase ; (d) command current and measure current in phase .
