Abstract:
This article concerns an improved vector control model. This model is developed
in a phase which comes just before the phase of its integration on electronic
boards such as those with Field Programmable Gate Array (FPGA) or Digital Signal
Processor (DSP). The innovative character of this model is based on the
replacement of the average model of the Direct Current (DC) to Alternating
Current (AC) converter powering a synchronous motor with permanent magnets by a
precise model considering the transient model of the power transistors,
electromagnetic switches, and diodes. The overall model generates the six DC-AC
converter control signals to regulate the speed of the permanent magnet
synchronous motor (PMSM) using the technique of back electromotive forces
compensation to reduce the power chain energy consumption for variable
rectilinear speed operation. This model makes it possible to consider the role
of diodes. This phenomenon is not considered by the average models of static
DC-AC converters considering that the power transistors conduce bidirectionally.
This model avoids all types of sensors that are usually used, such as current
and speed sensors.
