In this paper a state feedback controller for tubular linear permanent magnet synchronous motor (TLPMSM) containing two gas springs, is presented. The proposed TLPMSM controller is used to control reciprocating motions of TLPMSM. The analytical plant model of TLPMSM is a multi-input multi-output (MIMO) system which is decoupled to some sub single-input single-output (SISO) systems, then, the sub SISO systems are converted to sub-state space models. Indeed, the TLPMSM state space model is decoupled to some sub-state spaces, and then, the gains of state feedback are calculated by linear quadratic regulation (LQR) method for each sub-state space separately. The controller decreases the distortions of the waveforms. The simulation results indicate the validity of the controller.

Interior Permanent Magnet

This paper presents a nonlinear adaptive backstepping current hysteresis speed controller which can be used in both the constant-torque region and the field-weakening region for an interior permanent magnet synchronous motor (IPMSM). By using the proposed method, the adjustable speed range can be extended to 4 times that of the base speed. In addition, the d-axis current is suitably adjusted to increase the output torque of the IPMSM. Simulation results show that the implemented system has satisfactory performance, including good transient responses, good load-disturbance-rejection responses, and good tracking ability.
