You will be introduced to analysis and design of a feedback control systems. You will study stability and performance of interconnected systems, using Root Locus and Bode plots. You will design a combination of different controllers using proportional, integral or derivative gains. Furthermore, you will develop a phase lag or phase lead compensator. You will also develop simulation techniques for implementation of computer based control systems. You will also study and develop a Digital control system and study the effect of time sampling.

Learning Strategy

In this module the learners will engage in a blend of delivery methods facilitating both individual and collaborative aspects of learning to achieve the specified learning outcomes. In particular, this will require the learner to engage with the VLE materials where the learning is supported by the tutor-led two-way asynchronous discussion board. To focus the guided learning process, the tutor will set weekly quizzes/assignments (SAIL). These two elements will culminate in face-to-face sessions which will reinforce the learning by clarifying the content through student-led questions/answers interaction. These sessions are followed up by tutorials to illustrate the module content and enable practice in more depth. Theoretical material to be presented in lectures, with tutorial backup and directed reading. A series of practical exercises reinforced with sessions on the simulation and modelling of systems using both MATLAB standard functions and MATLAB programming. The formative nature of the assessment will arise from interaction with the students during the exercises. The module is supported by the use of BrightSpace VLE including course documentation, pre-recorded lectures, external links, communication/discussion and self-assessment facilities. Students with disability will be accommodated by close adherence to the University of Huddersfield guidelines which inter alia include: (i) pre-recorded materials with captions of suitable size, (ii) Power Point slides following the appropriate font size and colour contrast, (iii) early availability of all materials on VLE – typically at least two weeks in advance.
