Nonlinear position controller design with input-output linearisation technique for an interior permanent magnet synchronous motor control system

摘要: A novel, advanced position controller design for an interior permanent magnet synchronous motor control system is proposed. The input-output linearisation technique used to transfer the model into a linearised model. Then, based on model, H infin designed achieve robust performance of system. To improve performance, load estimator compensate external and influence parameter variations as well. In addition, maximum torque/ampere applied increase output torque motor. digital signal processor, TMS 320LF2407, execute speed-loop position-loop algorithms. As result, hardware circuit quite simple. Several experimental results show that proposed has fast transient responses, good disturbance rejection responses tracking responses.
