| Izvleček: | This paper investigates the possibilities for the design of current control for VSI from the discrete event point if view. Event-driving determines the transistor switching pattern directly from the current error logic signals change and is designed using a novel matrix based approach for the description of the discrete event systems. A new approach for description of event-driven systems is introduced. It is based on matrix description of Petri Nets, supplemented with a combination of logic and algebraic equations. The control algorithms designed by proposed approach can be easily implemented on modern DSP an FPGA devices. Instead of traditional coding, the control algorithms are loaded in the form of logical matrices. Such implementation does not include time consumptive A/D converters and transistorduty cycle algebraic calculations which significantly reduces the modulator calculation efforts. The approach is illustrated by the design of direct current controller for a three phase inverter fed Permanent Magnet Synchronous Machine and is examined by simulations. |
