| Abstract |
This paper investigates the possibilities of the
design of current control for VSI from the discrete event
point of view. Event-driven control approach determines the
transistor switching pattern directly from the current error
logic signals 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. The approach is illustrated with the design
of direct current controller for a three phase inverter fed
Permanent Magnet Synchronous Machine and is examined
with simulations and experimentally confirmed. |
