To solve the uncertainty of parameter variations and load disturbance
a nonlinear decoupling control based on disturbance suppression is presented for the permanent magnet synchronous motors drive system
where the adaptive control is combined with nonlinear decoupling control
and the parameter variations and load disturbance are regarded as the disturbance input. The state feedback adaptation law and parameter adaptation law are designed with Lyapunov theory to ensure the system convergence and the asymptotic tracing based on L
2
transient characteristics. The simulation and experiments show the greatly improved dynamic performance
robustness and anti-disturbance capacity of the system.
