Homogeneity-Based Higher-Order Sliding Mode Controller Design for Permanent Magnet Linear Synchronous Motor
نویسندگان
چکیده
-The permanent magnet linear synchronous motor (PMLSM) is sensitive to various disturbances such as the load disturbances, parameter perturbations, end effect and so on. To overcome this trouble, a new nonlinear robust controller using the homogeneity-based higher-order sliding mode control technique for the PMLSM is proposed. The detailed systematic controller design procedure is discussed. A digital-signal-processor (DSP) –based PMLSM position control system is implemented. The simulation and experimental results under different parameter and load variations are discussed and compared. The proposed control system shows good robustness and high accuracy in spite of the uncertainties, which confirms the theoretical analysis. Key-Words: PMLSM, homogeneity, higher-order sliding mode, DSP
