| DESCRIPTION | This study-unit continues upon SCE3113 in presenting further techniques for the analysis and design of automatic control systems in continuous-time and discrete-time. The design of analogue lag, lead and lag-lead compensators operating in continuous-time is presented using both open-loop and closed-loop frequency response approaches. This is followed by the presentation of direct digital control design techniques for computer-controlled systems using the polynomial pole placement, the root locus and the frequency response approaches. Study-unit Aims: The aims of the study-unit are to: - present the use of passive lag, lead and lag-lead compensators for control of systems in continuous-time, - apply the closed-loop and open-loop frequency response approaches for the design of lag, lead and lag-lead compensators, - present the polynomial pole placement digital control algorithm and its design, - present the use of the root-locus method in the z-domain for the design of digital control, - present the use of the frequency response approach in the discrete-domain for digital compensator design. Learning Outcomes: 1. Knowledge & Understanding: By the end of the study-unit the student will be able to: - identify the type of controller required to satisfy a given closed-loop system specification, - describe the effect of standard types of controller on the performance of a given closed-loop system, - distinguish between the use of continuous-time and discrete-time control approaches when presented with a control-design problem, - distinguish between emulation design and direct digital control when presented with a discrete-time closed loop control problem. 2. Skills: By the end of the study-unit the student will be able to: - apply an open-loop frequency response approach to design an appropriate compensator when presented with a performance specification for a given closed-loop control system operating in continuous-time, - apply a closed-loop frequency response approach to design an appropriate compensator when presented with a performance specification for a given closed-loop control system operating in continuous-time, - apply a direct digital control approach, utilizing the polynomial pole placement, root locus or frequency response method, to design an appropriate controller when presented with a performance specification for a given closed-loop control system operating in discrete-time.
