In this study, a new control approach for real-time speed synchronisation of multiple induction motors during acceleration and load changes is developed. The strategy to stabilise tracking each motor while synchronising its motion with other motors' motions so that differential errors among converge zero. An adjacent cross-coupling architecture incorporating sliding mode method proposed, the asymptotic convergence zero both have been realised via Lyapunov stability analysis. Performance comparisons PI decoupling are investigated on four-motor system. Simulation results show effectiveness proposed strategy.
