Motor Control Solution for Embedded Electric Drives
Overview
The Motor Control Solution is a collection of parameterized Matlab/Simulink models designed for functional modeling and control of electric machines. It supports both motor and inverter modeling, as well as field-oriented control (FOC) strategies. Direct integration with the μVOS real-time operating system is achieved through a specialized code generation toolbox, producing efficient, instrumented embedded code suitable for resource-constrained controllers.
The models derive control parameters from the physical properties of the motor and power electronics, eliminating the need for rotor position sensors. With support for real-time diagnostics, self-calibration, and soft-start mechanisms, the solution ensures high efficiency, robustness, and rapid deployment across automotive, industrial, and robotic systems.
