Position Control of Linear Switched Reluctance Actuator With a Digital Signal Processor

摘要

Linear Switched Reluctance Actuators (LSRA) with an adequate control strategy can be used in robotic applications. This application demands for position control capability. A first actuator topology is proposed, analysed and characterised. Based on it, design project and main functional performance characteristics are obtained. Specific instrumentation for actuator data acquisition is developed, using a Digital Signal Processor, TMS320F2812 from Texas Instruments, being implemented a control strategy that allows the control of the device movement. Obtained results made possible the understanding of actuator behaviours. The knowledge of a chosen set of experimental obtained characteristics, here presented, allows the proper actuator driving and control. Presented results will contribute for a different device topology that seems to increase actuator performance.
