Switched Reluctance Motor Based On Dspace Control System Research And Development

Switched Reluctance Motor (SRM) is a new type of motor, which is developed rapidly since the 1980s and has been widely used in the industry, aerospace and other fields. Due to its simple structure, wide velocity modulation range, excellent performance and high reliability,Switched Reluctance Drive (SRD) system had become a hot spot in motor control field. As an important component of SRD system, SRM controller determines system performance directly. Consequently, how to design and develop the SRM controller reasonably, rapidly and accurately had become an important issue.In this paper, SRM and the driving principle is introduced at first, as well as the motor model, development and research focus.Secondly, dSPACE, which is a type of real-time simulation tool and produced by a German company, is introduced in this paper, including its hardware components, software environment, real-time simulation function and the steps of using dSPACE to develop control algorithm. And we conclude that the development progress of SRM control system can be apparently accelerated by using hardware-in-the-loop simulation (HILS) technique based on dSPACE.Afterwards, the design and development method is presented. A simulation platform based on dSPACE is constructed and the main research in this platform as follows.1. Simulation model and sub-model for the SRM controller is designed.2. Fuzzy control algorithm is researched for the SRM controller.3. Developing a set of 0.55kW SRM control system in order to testify feasibility and effectiveness of the SRD system using proposed method.4. Based on research above, the performance of SRD system is tested and analysed by a motor testing platform The experimental results show that the method proposed in this paper is feasible and valid.Finally, we draw a conclusion that the development.of SRM control system can be accelerated apparently by using hardware-in-the-loop simulation (HILS) technique based on dSPACE.
