Teaching

Advanced Control Systems (Postgraduate/Undergraduate)

This module introduces the advanced topics in control systems and the control engineering application in power electronic systems, automotive and robotics design. Topics include stability analysis of nonlinear systems, digital control systems, intelligent systems, model predictive control, adaptive control and variable structure control, estimator design and modeling and real-time simulation. This module will have labs either in the electronics lab, or in the ITL.

Electronic Engineering Mathematics I (Undergraduate)

This module covers linear algebra, vector algebra and analysis, and differential equations. Linear algebra includes: introduction to Matrices, addition of Matrices, multiplication of Matrices, Systems of Equations; Eigenvalues and eigenvectors. Differential Equations cover first and second order D.E, and vector algebra includes field operators and surface and volume integration in different coordinate systems. All topics will be related to engineering applications.
