Exact minimisation of large multiple output FPRM functions.

Journal Article
Almaini, A. E. A. & Wang, L. Y. (2002)
Exact minimisation of large multiple output FPRM functions. IEE proceedings. Computers and digital techniques. 149, 203-212. doi:10.1049/ip-cdt:20020674. ISSN 1350-2387
The properties of the polarity for sum-of-products (SOP) expressions of Boolean functions are formally investigated. A transform matrix S is developed to convert SOP expressio...

Adaptive PN code acquisition in multi-path spread spectrum communications using FPGA.

Conference Proceeding
Wei, B., Sharif, M., Binnie, D. & Almaini, A. E. A. (2007)
Adaptive PN code acquisition in multi-path spread spectrum communications using FPGA. In Proceedings of the 13th International Symposium on Signals, Circuits and Systems, 573-576. ISBN 978-1424409686
Performance of two pseudonoise (PN) code detectors was tested. Cell averaging (CA) and order Statistics (OS) constant false alarm rates (CFAR) were analysed against mean acqui...

Journal Article
Rashed, M., Goh, K. B., Dunnigan, M. W., MacConnell, P. F. A., Stronach, A. F., & Williams, B. W. (2004)
Sensorless second-order sliding-mode speed control of a voltage-fed induction-motor drive using nonlinear state feedback. IEE proceedings. Electric power applications, 152(5), 1127. doi:10.1049/ip-epa:20050042
A high-performance and robust sensorless speed-control scheme of a voltage-fed induction motor has been developed in which the control of speed and flux is decoupled. A robust...

Fault diagnostics using slide mode techniques.

Journal Article
Goh, K. B., Spurgeon, S. K. & Jones, N. B. (2002)
Fault diagnostics using slide mode techniques. Control Engineering Practice. 10, 207-217. doi:10.1016/S0967-0661(01)00114-9. ISSN 0967-0661
A sliding mode technique was developed and applied to analyse temperature sensor data to reveal faults. The advantage of the technique is that it allows other system parameter...
