Outline Of Syllabus

Introduction to Digital Control Fundamentals

Sampled signals, linear difference equations and discrete transfer functions, sample and zero order hold operations, quantisation effects, block diagrams, stability analysis techniques, signal analysis and dynamic response, discrete time specifications and their correlation with time and frequency domains, discrete equivalents to continuous transfer functions, different loop structures, regulation and serving functions.



Digital Control Designs using Classical Methods

Discrete time implementations of classical design methods, digital PID controller, root locus design technique, frequency response based designs, introduction to direct design methods.



Design using Modern Methods

z- plane specifications pole placement based design, introduction to minimum variance design concept, deadbeat objective and concept of control ripple. Serving versus regulation objectives. Practical implementation considerations.

Introduction to discrete state- space representation – e.g system matrix representation, observable, controllable and diagonal representation forms and their relationship to transfer function forms. Simple control law designs - using pole placement objective, introduction to concept of state estimation, design of state estimator and analysis of effect on control loop.

Advanced material drawn from: introduction to nonlinear dynamics, LMI, stochastic estimation (Kalman Filter), adaptive/self-tuning control, system identification and parameter estimation

Teaching Rationale And Relationship

There is a combination of lectures and practical sessions using CAD packages like Matlab/Simulink. Through this combined approach, students will be able to better understand and apply the concepts of advanced digital control systems. Tutorials provide students with the opportunity to apply knowledge and confirm the taught concepts. Tutorials typically align with the expectations of the examination. Self Directed Learning exercises provide students with the opportunity to explore complex problem based learning exercises using Matlab/Simulink. Self Directed Learning exercises also typically align with the expectations of the examination.



All face-to-face activities can be replaced with online synchronous sessions supported by non-synchronous recordings if the public health situation requires it.

Assessment Rationale And Relationship

The Practical Examination reflects the innovative combined teaching style and consists of a 24-hour open book exam. The examination requires students to have a formal knowledge of the basic principles of digital control systems, and a formal knowledge of using Matlab/Simulink in the design of advanced digital control systems. Whilst the format of the examination is the same for all students, each paper contains student specific design parameters. This yields a unique solution and conclusion set for each candidate.
