ECE2031 - Circuits and control

6 points, SCA Band 2, 0.125 EFTSL

Undergraduate Faculty of Engineering

Leader(s): Jingxin Zhang


Clayton Second semester 2009 (Day)
Sunway Second semester 2009 (Day)


the unit will provide a grounding in circuit theory leading to solution of electrical networks with node and mesh analysis, equivalent sources, two port representations and simulation. AC analysis with phasors, real and reactive power, first and second order transient responses will be included. Frequency and time response will be developed with Laplace transform techniques.

Feedback control systems are introduced using differential equations, Laplace transform, time, frequency and state space representations. the concepts of poles and zeros, forward transfer functions, and PID control will be developed. Stability of feedback systems, root locus diagrams, Nyquist and Bode techniques, gain/phase margin concepts, and distrubance rejection will be covered.


On successful completion of the unit students will be able to:

  1. Analyse and understand DC and AC electrical circuits.
  2. Perform and interpret circuit simulations
  3. Solve for an interpret the transient response of first and second order electrical circuits
  4. Model and analyse closed loop feedback systems
  5. Design and understand the significance of PID control
  6. Understand and analyse the stability of single input single output control systems.


Examination: (3 hrs), 70%. Laboratory and assignment work: 30%. Students must achieve a mark of at least 45% in each component to achieve an overall pass grade.

Contact hours

3 hours lectures, 3 hours laboratory/practice classes, and 6 hours of private study per week
