Adaptive Fractional-Order Anti-Saturation Synchronous Control for Dual-Motor Systems

The synchronization error of a dual-motor system will seriously affect the motion profile accuracy. To solve this problem, an adaptive fractional-order anti-saturation synchronous control method based on frequency-domain theory is proposed in paper. On one hand, performs compensation closed-loop feedback loop to unify characteristics for system. With characteristics’ unification module, have same response performance regarding input signal. other considering that nonlinear problem voltage saturation also cause asynchronization system, involves module prevent and eliminate effects. experimental results verify can accurately avoid effect effectively reduce with root-mean-square reduction 80.974%. Hence, provides effective solution high-precision
