Abstract:By using the energy dissipation theory and the property of the switched reluctance motor, this paper presents a nonlinear controller for the linear switched reluctance motors (LSRM). Based on the fact that the electrical time constant is much smaller than the mechanical time constant, the whole LSRM driving system is treated as a two-time-scale system and can be decomposed into two subsystems (electrical and mechanical) that are negative feedback interconnection. The controllers are designed for two subsystems respectively to ensure that they are passive. In view of the fact that the system made of two passive subsystem connected through negative feedback is still passive. Therefore, the stability of LSRM driving system is ensured in large scale. This control strategy possesses a simple structure and can be implemented easily. The experimental results show that the proposed control is effective and roboust for the position control of LSRM.
