Figure 15

Experimental results of PMSM direct-driven PMSG system using the modified Elman NN controller for the Δ connection three-phase loads of  Ω with  rad/s (  rpm) at case 2: (a) rotor speed ; (b) adjusting response of step desired magnitude of the DC bus voltage and actual measured magnitude of the DC bus voltage in output end of the rectifier; (c) adjusting response of step desired root-mean-square magnitude of the AC 60 Hz line voltage and actual measured root-mean-square magnitude of the AC 60 Hz line voltage in output end of the inverter ; (d) tracking response of the desired phase current and actual measured phase current in phase ai of the inverter.
