“…Voltage source inverters (VSIs) are widely utilised in driving the variable speed ac motors. Pulse width modulations (PWM) such as single carrier sinusoidal PWM (SPWM) [1], zero-sequence injection PWM [2], space-vector PWM (SVPWM) [3][4][5][6][7] and neural-network based SVPWM [8] have been proposed to generate the control commands of 3-phase VSI and applied to sensorless motor drive [9]. Further, multiphase PWMs are proposed due to the advantages of increased efficiency [10], reduced torque pulsation, lower dc link current harmonics, improved fault tolerance [11,12] and lower power handling requirement of power switches [3].…”

A multiphase space-vector pulse-width modulation (SVPWM) with switching states selected based on reference order is proposed. The immediate advantages include the great reduction of computational complexity and simple extension to arbitrary prime phase numbers. In the first part, the general switching strategy is derived considering pure sinusoidal references. Though the derived method is based on adjacent space-vector selection, unlike the conventional method, it needs not any information of sector number. Further, the duty ratio can be obtained from the N-phase reference directly without any information of selected switching states. The second part shows that the strategy is applicable to multi-frequency references. By comparing the proposed SVPWM with carrier-based PWM, the implementation of SVPWM becomes quite simple. In simulations and experiments, five different references are applied and the results verify the accuracy of the proposed modulator.

Maximum Torque Per Voltage trajectory has been utilized only during field weakening operation of Interior Permanent Magnet (IPM) motor. In this paper, the voltage minimization control from zero-speed is proposed. Voltage minimization results in maximum torque per voltage control of IPM motor. The control implementation is also simple in comparison to current minimization, as the operation is always along the current-limit locus irrespective of operation in field-weakening. Voltage minimization technique minimizes the core losses whereas current minimization would minimize the copper losses. The mathematical model of IPM motor following voltage minimization is derived and the solution to the 4 th order quartic equations is obtained using Ferrari's method. The solution obtained is utilized to develop a look-up table for vector control of IPM motor. A comparative analysis of voltage minimization and current minimization is established which is supported by simulation results and demonstrated by detailed experimental results.

“…For achieving high-performance current control of permanent magnet synchronous motors (PMSMs), accurate information of rotor position is usually required. In practice, the positionsensorless operation is preferred in hostile environments and lowcost applications [17,18]. Even equipped with a position sensor, a rotor position estimator is still required to achieve sensor faulttolerant control for safety or reliability reasons in some cases, such as in automotive applications [19].…”

Robustness against parameter mismatches and position-sensorless operation are two important research topics for permanent magnet synchronous motor (PMSM) drives. In this paper, a sliding mode disturbance observer (SMDO) is proposed to achieve either of two functions for different application environments: 1) if a position sensor is equipped, accurate current regulation can be achieved by deadbeat predictive current control (DBPC) despite mismatched motor parameters; 2) if the position sensor is not equipped but with a good estimation of motor parameters, the observer can serve as a back electromotive force (EMF) estimator. On this basis, the rotor position can be extracted for positionsensorless control. Usually, low-pass filter is required to suppress high frequency noises in conventional sliding mode observer. This inevitably leads to phase delay in the estimation, which cannot be directly used for disturbance compensation. While in the proposed method, a complex coefficient filter is inherently embedded, which can provide accurate estimation without phase or magnitude error. Experimental results obtained from a 2.4 kW PMSM drive platform indicate that high performance current control can be achieved with good robustness for position sensor based operation. And, rotor position can be accurately estimated with good steady and dynamic performance for position-sensorless operation.
