Nonlinear dynamics control for a single-phase voltage source inverter based on target-oriented control with control actions frequency reduction

A technical implementation variant of a singlephase voltage source inverter control system with sinusoidal pulse-width modulation based on target-oriented control with control actions frequency reduction providing specified nonlinear dynamic properties of the sys-tem and reduced requirements for computing resources of the microcontroller. The control system under consideration provides sinusoidal output voltage of the inverter in a wide range of variation of the system parameters. This makes it possible to exclude undesired dynamic modes without application of parametric synthesis. The proposed method of nonlinear dynamics control for systems with sinusoidal pulse-width modulation is used for the first time and provides a number of advantages in comparison with the known methods.
