ST releases free motor control algorithms
12 November 2008
Design Automation
STMicroelectronics has extended its library of functions supporting vector control of electric motors using the 32-bit STM32 microcontroller (MCU), with new turnkey algorithms supporting single-shunt sensorless control, control of IPM (internal permanent magnet) motors, and field-weakening controls for PMSMs (permanent magnet synchronous motors).
The additional library functions, now available in the STM32 motor control library version 2.0 aims to enable optimal motor selection and a larger operating envelope in appliances, industrial drives, pumps, HVAC systems, vending and cash machines, and electric vehicles.
At the same time, ST has extended access to the motor-control library from third-party tool chains, by adding support for the Keil, IAR and Green Hills STM32 design environments. The software library is available free of charge upon request, and can be used directly with the STM3210B-MCKIT hardware evaluation and development kit for motor-control applications based on the STM32.
Among the new algorithms now available to designers, support for single-shunt current sensing eliminates two of the three current-sense resistors from conventional sensorless control schemes. Single-shunt sensing is a patented technique developed by ST, which delivers additional benefits of high DC-bus voltage use, minimum current distortion, and low audible noise. By also adding a maximum-torque-per-ampere algorithm, the extended library gives designers extra freedom to specify brushless IPM motors in applications requiring the high power density and very high-speed capabilities of these devices.
Also new is stator-voltage closed-loop field-weakening control. This reduces sensitivity to motor parameter and environmental variations, thereby expanding the operating limits of all types of PMSM motors. On top of this, feed-forward control compensates bus-voltage ripple and improves current regulation during high-speed flux-weakening operations.
