1. Control strategy
The asynchronous machine is often powered by a voltage inverter with forced-switching semiconductor components controlled by pulse-width modulation (PWM), a DC voltage slicing technique that supplies the machine with waveforms whose mean value evolves sinusoidally.
The control diagrams in figures 1 and 2 show that there are two control chains.
Each chain comprises a control variable (voltage
