This unit will cover the following:

This unit introduces foundational concepts in control engineering, focusing on feedback systems, stability, and dynamic system behaviour. Students will learn key analysis and design techniques for feedback control systems, including PID control, root locus analysis, and the Nyquist stability criterion. The unit will equip students with the skills necessary to analyse and design control systems using both time-domain and frequency-domain methods. Additionally, students will gain practical experience in control system design and implementation through laboratory experiments, utilizing control system analysis and design software.

The key topics covered in this unit include:

- Dynamic system representation using transfer function model 
- Step/impulse responses of first- and second-order systems 
- Single-input, single-output (SISO) control structures 
- Proportional (P), PI, PD, and PID control design 
- Root locus analysis
- Steady-state response to sine-wave input, Bode plots 
- Nyquist plot, Nyquist stability criterion
- Gain Margin, Phase Margin 
- Design of phase lead and phase lag compensators  
- Conversion of continuous-time controllers to discrete-time representation for implementation on digital computers 

The course unit aims to: - Introduce students to the key concepts in control engineering, focusing on feedback systems, stability, and dynamic system behaviour.

- Explore analysis and design techniques for feedback control systems, including PID control, root locus analysis, and Nyquist stability criteria.

- Equip students with the skills to analyse and design control systems using both time-domain and frequency-domain approaches.

- Introduce students to the process of converting continuous-time controllers into discrete-time representations for implementation on digital computers.

- Provide practical experience in control system design and implementation through laboratory experiments utilizing control system analysis and design software. 

All ILOs are developed and assessed.

ILO 1: Represent dynamic systems using transfer function model, and analyse their steady-state and transient behaviour. 

ILO 2: Design and tune proportional, PI, PD, and PID controllers for low-order dynamic systems, ensuring the desired closed-loop system behaviour and performance. 

ILO 3: Determine the stability of closed-loop systems using Bode plots, Nyquist Stability Criterion.

ILO 4: Design phase-lead and phase-lag compensators and assess the performance of the resulting closed-loop system in both time-domain and frequency-domain.

ILO 5: Convert continuous-time controllers into their discrete-time representation. 

ILO 6: Implement feedback control systems in laboratory sessions, and evaluate their performance in terms of stability, response time, and robustness.
