синхронна машина з постійними магнітами

This work presents the electric control system for electric vehicle drive based on the strategy of direct torque control of a synchronous machine with permanent magnets. In order to provide energy efficiency in the first zone of angular speed regulation, the reference of the armature flux is formed depending on the current value of the electromagnetic torque of the machine.

Main energy-based methods for synthesis of control systems of port-controlled Hamiltonian systems were considered, in particular: passivity-based control, energy-balance approach, interconnection and damping assignment and their combination with elements from linear and nonlinear control system theory. There are shown examples of using such methods for nonlinear object — permanent magnet synchronous machine. Result of their computer research and detail analyzes are presented as well.
