High precision multi induction motor control is one of the key issues in modern industry and motion control field.Induction motor model is multi-variable and nonlinear,while the simplified one-order induction motor model is widely used in current multi-motor control area,which cannot satisfy the requirements of high precision multi-motor control.Sliding-mode control method was adopted incorporating adjacent cross-coupling control structure in the proposed control strategy based on 4-order field-oriented induction motor model, and a simple technique was used to eliminate the chattering phenomenon within sliding-mode control. Comparing with PID control under adjacent cross-coupling control structure, simulation results illustrate the effectiveness and robustness.
