摘要
In order to eliminate the influence of parameter uncertainties on field-oriented control for induction motor drive, a sliding-mode speed controller with integral sliding surface is proposed. In this proposed control scheme the sliding-mode control strategy is worked in conjunction with the field-oriented control method to improve the controller performance. The estimated rotor speed used in speed feedback loop is calculated by an adaptive algorithm based on measured terminal quantities. Stability analysis based on Lyapunov theory is presented to demonstrate that the rotor speed is exponential convergent. Simulation results are also presented to confirm the characteristics of the proposed overall control scheme.
