Adaptive Fuzzy Terminal Sliding Mode Control for Permanent Magnetic Synchronous Motor of Electric Locomotives
摘要
Abstract
For the study of speed control precision for permanent magnetic synchronous motor(PMSM)on electric locomotives during traction,a mathematical model of PMSM was established in the d-q coordinate system after considering unknown radially time-varying load torque of wheel-set generated by wheel rail contact irregularity and static weight of locomotive body. Nonlinear torque observe(r NTO)was designed to estimate the actual value of the time-varying torque with the observation error derivatives approached by adaptive fuzzy logic system. According to the Lyapunov stability theory,adaptive fuzzy terminal sliding mode controller with NTO was constructed after the introduction of quasi potential energy function in sliding mode surface. Simulation results demonstrate that the PMSM speed control system has uniformly bounded error with slight dynamic buffeting of axle voltage and axle current,and the torque observation error is constricted to 0.关键词
