The Hybrid RFNN Control for a PMSM Drive Electric Scooter Using Rotor Flux Estimator

Figure 7

Experimental results due to a 𝑇_𝐿=2 Nm load torque disturbance with load and shed load at 2400 rpm: (a) command rotor speed 𝜔^∗, measure rotor speed 𝜔_𝑟, and measure current 𝑖_𝑎 in phase 𝑎 using a PI control system; (b) command rotor speed 𝜔^∗, measure rotor speed 𝜔_𝑟, and measure current 𝑖_𝑎 in phase 𝑎 using HRFNN control system.
