Abstract :
A novel feedback control scheme for speed regulation of permanent magnet synchronous motor (PMSM) is investigated under port-controlled Hamiltonian (PCH) and finite-time terminal sliding mode (TSM) stabilization theory. The desired equilibrium is assigned to the PCH structure model of PMSM by maximum torque per ampere (MTPA) principle, and the desired Hamiltonian function of state error is constructed in the form of fractional power structure as TSM. Finite-time TSM control is designed via interconnection and damping assignment passivity-based control (IDA-PBC) methodology with PCH theory. Finite-time stability of the desired equilibrium point is also proved. Simulation results validate the improved performance of the presented scheme.
