Abstract：To solve the problem of angular servo control of permanent magnet synchronous motor (PMSM). Based on the control model of PMSM expressed in direct-quadrature (dq) coordinate frame, the command filtered backstepping (CFBS) method is employed for controller design, so the derivatives of virtual control variables can be approximated by a stable second-order filter which can avoid the increasing complexity in calculating the analytic derivatives of the virtual control in conventional backstepping method. A filtered error compensation loop is designed to guarantee that the filtered signal can precisely track the reference input signal. The robust schemes are designed through Lyapunov stability analysis with guaranteed stability for the close-loop of tracking errors, while the particle swarm algorithm is adopt for the optimization of controller parameters. Finally, the simulation results are presented to illustrate the effectiveness of the proposed control method with accurate tracking performance.
