| Abstract |
To assume the digital regulation of the output voltage of a PWM inverter, the authors present a
complete methodology for the design of a control law allowing to take into account the current
limitation and perturbations such as the dead time of commutation of the IGBT. In this paper the
control law proposed is organized around two feedback control loops: a primary loop dealing with the
output voltage and a secondary loop controlling the output inductance current. The controller
coefficients are easily obtained by a simple matrix inversion, thus enabling a relatively easy
implementation of the automatic regulator parameter computation. |
