Multi-phase electric machines such as five-phase permanent magnet synchronous motor (PMSM) play an important role in the ships electrical propulsion because of the advantages of high performance and high reliability. The decoupled mathematic models of five-phase PMSM in dq coordinate frame are established, and the reason caused to high stator harmonic current in the multi-phase motor is analyzed based on the mathematic models. To suppress the harmonic current, a novel vector control (VC) method based on SVPWM and harmonic current closed loop control is proposed. Based on the proposed algorithm, a five-phase PMSM vector control system is established with MATLAB, the performance is simulated and analyzed. The results show that, the stator harmonic current is much little than that of the traditional control method.

Permanent magnet synchronous machines have been universally used over induction machines in variable speed drives. For present trends and future developments, power electronics technology gives the extensive research of multilevel inverters that brings high safety voltages with low harmonic content in comparison with two-level inverter strategies. Multi level inverters implementation can be done by raising the number of power semi conductor controlled switching devices per phase to increase the number of inverter output voltage levels. By increasing the levels, power controlled switching devices and other components are increased, which makes the inverter complex and overpriced. From the above aspects, three-phase three-level inverter strategy is used for high performance and high voltage A.C drives. Multilevel inverter using a space vector pulse width modulation (SVPWM) strategy gives great advantages in high performance A.C drive applications. Various types of control strategies have been recommended for voltage source inverter fed A.C drives. In the proposed work, a PI controller is designed for the outer loop and non-linear controller using a state feedback linearization technique is designed for the inner loop. The closed loop control system for three-level inverter fed Permanent magnet synchronous motor drive employing SVPWM is extensively simulated using MATLAB.

Robust and reliable control of robotic manipulators is studied. A model-based precompensation configuration is first used to decouple and linearize the highly complicated electromechanical dynamics of robotic manipulators. Then a linear state-feedback control law is used for closed-loop control. Finally, simplified SMC is adopted to postcompensate for the resulting error dynamics of the closed-loop control system. It is shown that the intentionally introduced control redundancy will not only ensure global high performance for the resulting system, but will also provide the system with built-in high reliability.

At present, the pure electric vehicles with a permanent magnet synchronous motor (PMSM) vector control (VC) and direct torque control (DTC) are mainly control method. These two kinds of control mode are considered as a high performance PMSM control strategy which has been widely used in practice [5]. Starting from the mathematical model of PMSM, two kinds of control strategies are to be the theoretical analysis, so that the control thoughts and the composition of control system has a profound understanding to applies two kinds of strategies to control of PMSM. Simulink modeling and simulation results proved that vector control is better than that of direct torque.
