In this study, an easily implementable and effective method in loss-minimisation control of interior permanentmagnet synchronous motors (IPMSMs) is proposed. Complication of loss-minimisation condition and its implementation are main problems in model-based control methods of IPMSMs. To resolve these problems, an approximate-model is used for simplification of loss-minimisation condition and a proportional-integral-controller is utilised to directly solve the loss-minimisation condition. Also, saturation and iron loss resistance variation due to frequency variation are considered in the proposed method. Furthermore, results show the high precision of the proposed method in comparison with accurate model. Steady-state performance of the proposed method is compared with look-up tablebased loss-minimisation and maximum torque per ampere (MTPA) control methods. Also, experimental results verify performance, good dynamic response and effectiveness in loss reduction of the proposed method under different conditions in comparison with look-up table-based loss-minimisation and MTPA control methods.

“…According to these advantages, PMSMs are widely used in industrial drive applications, mainly for efficiency improvement [2][3][4][5]. There are some methods to control PMSMs such as i d = 0 method [6], unity power factor [7,8], maximum torque per ampere (MTPA) [9][10][11][12][13], loss-minimisation etc.…”

“…In Fig.9 (bΨ, both the d and q-axis currents get to the expected level quickly after discharge begins and then, they level off until about 4.9 s when the bus voltage is not able to maintain such high current level. Due to the cross-coupling effect [34], the magnitude of the q-axis current experiences a short-period increase before it declines to zero, while the d-axis current continuously decreases because of its large value. Fig.9 (cΨ shows that the bleeding current passing through the BR (BR currentΨ jumps to about 16 A at first.…”

When electric vehicles (EVs) encounter an emergency, the voltage of the DC-bus capacitor in the surface-mounted permanent magnet synchronous motor (SPMSM) based powertrain requires to be reduced as fast as possible. In order to eliminate the disadvantages and s y n t h e s i z e t h e a d v a n t a g e s o f t h e t r a d i t i o n a l m a c h i n e winding-based and external bleeder-based discharge techniques, this paper proposes a hybrid discharge strategy which can achieve five-second discharge in minimum sacrifice of the bleeder size and weight for any EV drives. For the purpose of evaluating the size reduction of the new method, the individual bleeder-based scheme is modelled and analyzed at first. Then, the combined discharge method is developed, which contains two sequential procedures: bleeding resistor (BR) design and discharge control algorithm design. The BR design process has to be implemented under the extreme condition. But concerning that the emergency might occur at the moment when the machine operates below the maximum speed, three different discharge modes including full-power, partial-power and bleeder-based discharge modes are developed. The proposed discharge techniques are verified by experiments which are conducted on a three-phase SPMSM drive system used for EVs.

“…To avoid the catastrophic failure of the encoder and sensor, a novel backup universal sensor concept for PMSM with position and current estimation has been presented in [225]. An improved algorithm has been developed for obtaining the maximum torque by accounting the core loss, cross-coupling effect and temperature for PMSM drive [226].…”

The rapid consumption of fossil fuel and increased environmental damage caused by it have given a strong impetus to the growth and development of fuelefficient vehicles. Hybrid electric vehicles (HEVs) have evolved from their inchoate state and are proving to be a promising solution to the serious existential problem posed to the planet earth. Not only do HEVs provide better fuel economy and lower emissions satisfying environmental legislations, but also they dampen the effect of rising fuel prices on consumers. HEVs combine the drive powers of an internal combustion engine and an electrical machine. The main components of HEVs are energy storage system, motor, bidirectional converter and maximum power point trackers (MPPT, in case of solar-powered HEVs). The performance of HEVs greatly depends on these components and its architecture. This paper presents an extensive review on essential components used in HEVs such as their architectures with advantages and disadvantages, choice of bidirectional converter to obtain high efficiency, combining ultracapacitor with battery to extend the battery life, traction motors' role and their suitability for a particular application. Inclusion of photovoltaic cell in HEVs is a fairly new concept and has been discussed in detail. Various MPPT techniques used for solar-driven HEVs are also discussed in this paper with their suitability.
