• ### Capacitor energising transient limiter for mitigating capacitor switch-on transients

Publication Year: 2011, Page(s):260 - 266
Cited by:  Papers (7)
| | PDF (563 KB)

Capacitors are prone to two major types of energising transient phenomenon: transient overvoltage and inrush current (charging current). Energising transients will shorten the lifetime of the capacitor, and furthermore they will damage the contacts of the switching device. This study proposes a rectifier type capacitor energising transient limiter (CETL) for mitigating the isolated capacitor and b... View full abstract»

• ### Measurement method for online battery early faults precaution in uninterrupted power supply system

Publication Year: 2011, Page(s):267 - 274
| | PDF (333 KB)

There have been many studies written about the methods used to determine the health of batteries in offline application. This study intends to apply the voltage tracing method to produce a simple method in determining the early faults of online battery. The results showed that by using the voltage tracing method, it is possible to find the early faults of batteries, which in turn can prevent power... View full abstract»

• ### Improved predictive current control for unbalanced stand-alone doubly-fed induction generator-based wind power systems

Publication Year: 2011, Page(s):275 - 287

| | PDF (1539 KB)

This study proposes an improved predictive current control (PCC) strategy for unbalanced stand-alone doubly-fed induction generator (DFIG)-based wind power systems. The proposed control scheme predicts an appropriate average rotor voltage vector in next switching period to eliminate the rotor current errors in the following control period. The identified voltage vector sequence is then applied to ... View full abstract»

• ### Mono inverter multi-parallel permanent magnet synchronous motor: structure and control strategy

Publication Year: 2011, Page(s):288 - 294
Cited by:  Papers (14)
| | PDF (628 KB)

This study presents a new and original Mono inverter multi-parallel permanent magnet synchronous motor (PMSM) system. To obtain the stability of such a system, each of the motor synchronisms should always be respected regardless of their load torque. In this case, only one motor, called master motor, will be self-piloted. If the chosen master motor is the one with the highest applied load torque... View full abstract»

• ### Adaptive supervisory Gaussian-cerebellar model articulation controller for direct torque control induction motor drive

Publication Year: 2011, Page(s):295 - 306
Cited by:  Papers (3)
| | PDF (956 KB)

This study develops an adaptive supervisory Gaussian-cerebellar model articulation controller (ASGCMAC) and implements it in a sensor-less direct torque control (DTC) system for controlling induction motor speed. The inherent uncertainties of a DTC system, including parametric uncertainties and the uncertainties in external load torque, make control tasks difficult. A model-free approach, ASGCMAC,...

• ### Operating points estimation of three-phase induction machines using a torque-speed tracking technique

Publication Year: 2011, Page(s):307 - 316
Cited by:  Papers (2)
| | PDF (466 KB)

An algorithm implementing a behavioural modelling technique for estimating the parameters of induction machine models is proposed. This technique, called torque-speed tracking, starts from manufacturer data and solves the identified problems which are caused by the lack of operating points and by the method used to minimise the torque error. The proposed technique is implemented for both single- a... View full abstract»

• ### Design of high-torque-density double-stator permanent magnet brushless motors

Publication Year: 2011, Page(s):317 - 323
Cited by:  Papers (20)
| | PDF (789 KB)

This study proposes and implements an optimal design approach for the double-stator permanent magnet brushless motor. The key is to optimise the split ratio, namely the ratio of the inner-stator outside diameter to the outer-stator outside diameter, of this motor in such a way that the maximum torque density can be achieved. Both finite-element analysis and experimental results are given to verify... View full abstract»
