Overview

This unit introduces the principles and applications of feedback control systems. Students will explore key topics such as low-sensitivity design, dynamic response, and closed-loop stability. Analytical techniques including the Routh–Hurwitz stability criterion, root locus, and frequency response analysis will be applied to assess system performance in terms of stability and dynamics. Various controllers—Proportional (P), Proportional–Integral (PI), and Proportional–Integral–Derivative (PID)—as well as lead, lag, and lag–lead compensators will be designed and evaluated in both time and frequency domains. The unit also introduces state-space modelling and the conversion between state-space and transfer function representations, equipping students with modern control analysis and design skills.

Learning Outcomes

On successful completion of this unit, students will be able to:

  1. Discriminate between open-loop and closed-loop control systems and explain their functional requirements;
  2. Derive and simplify system transfer functions using Mason’s Gain Formula and block diagram reduction techniques;
  3. Apply the Routh–Hurwitz stability criterion and root locus methods to analyse and assess system stability;
  4. Evaluate system behaviour and relative stability through time-domain and frequency-domain techniques; and
  5. Design and tune P, PI, PID, lead, lag, and lag–lead compensators to achieve desired performance specifications for Linear Time-Invariant (LTI) systems.

Assessment

For Melbourne campuses

Assessment type: Laboratory Work
|
Grade: 40%
Lab Report (Group) (2000 words)
Assessment type: Test
|
Grade: 60%
Two in-class invigilated tests (30% each, 60 minutes each) (Individual)

Tests: These secure invigilated in class assessments have an unpredictable problem-solving scenario format that tests deep understanding, requires explanation of reasoning and process, and involves applying knowledge to new contexts.

Laboratory Work: Structured group lab report documenting progressive design, implementation, and validation processes in detail. Progressive milestone checks, documented collaboration and individual contributions ensure accountability and support verification of each student’s engagement. Explicit evaluation of individual contributions further supports the assessment and assurance of each student’s achievement of learning outcomes.
