Design and analysis of a dSPACE-based position control system for a linear switched reluctance motor

This paper presents a high-precision position control system for a linear switched reluctance motor (LSRM) based on dSPACE real-time control platform. The LSRM has a very simple structure and it can be manufactured easily, and there is no need for magnets. The control system utilizes dSPACE development platform as the controller and generates the real-time code for the control algorithm and motor model, tuning the control parameters online and PD algorithm is implemented. The experiment results indicate that with the control method presented in the paper, the position error is less than 0.04 mm. Also compared with traditional research and development method, using dSPACE real-time control platform is able to quickly complete research and development for this kind of position control system, and the advantages are not only to shorten the entire system development cycle but also ensure system reliability and reduce costs.
