Implementation of the permanent magnet synchronous motor vector control implies strong time dependencies. The control process requires precise measurement of motor shaft position and winding currents to establish correct driving. The tight time dependencies are difficult to achieve using a programmatic approach. Specific controller architecture is proposed for programmable systems on chip architectures enabling operations precise timing and improved processing performance. The controller is decomposed into a dedicated hardware interface system and programmatic part for easy implementation and modification of the control algorithm. The proposed architecture offers precise and repeatable input-output operations timing and assures meeting tight time dependencies. The control algorithm is executed as an interrupt service requested by the interface system in a constant processing period with relatively weak time dependencies. Additionally, the interface system preprocesses input and output signals reducing the computation effort and saving time for algorithm computations. The specific implementation enabled improved measurement of the motor’s windings current with suppression of disturbances caused by inverter operation. There is shown an efficient implementation of Parke’s and Clarke’s transformations using specific resources of modern programmable logic devices. In opposite to the software-managed implementation presented implementation assures completing processing faster, using a minimal number of hardware resources of the FPGA platform and offering the highest flexibility of software part implementation. |
