This site contains links to resources for an introduction to control analysis for second year engineering undergraduate.The main focus is on block diagrams, offsets, pole computations, understanding stability/instability, root-loci, bode, nyquist, margins and an introduction to lead and lag compensation. The focus is on analysis not design which is covered in a later course. The resources here include the lecture hand outs which include embedded tutorial questions, some powerpoints for structuring lectures, some games/quizzes for lectures, a MATLAB laboratory based on significant prior practice, a FLASH lecture and then a formal laboratory test under exam conditions and a small data base of CAA developed on webct (here provided in a zip file). These were developed at the University of Shef

Description

Overview: This learning object is a simulated laboratory experiment (experimental investigation of pressure measurements), which closely mimics the features of actual laboratory apparatus for measuring pressure, with an output of the associated data. The unlimited model scenarios provide realistic experience with the opportunity for deep learning. Appropriateness: Students studying Engineering at the Faculty of Advanced Technology undertake a 10-credit module aiming to give a basic introduction to instrumentation and its applications. The assessment used to address this learning outcome is a laboratory assignment in which students are required to calibrate a pressure sensor and subsequently use it to investigate transient pressure response of a pneumatically charged system. In this respect

Description

These resources cover an introduction to modelling for first year engineering undergraduate. The main focus is on electrical and mechanical systems, but there is also some discussion of dc motors, fluids and heat as well as an introduction to time series modelling. The main emphasis is on why modelling is important and how to go about doing this from first principles (e.g. Kirchhoff's laws, Newton's Laws, etc.). Given the focus is on new students arriving at University, there is no attempt to develop models beyond second order. The resources here include the lecture hand out (pdf) which includes embedded tutorial questions, some powerpoints for structuring lectures , flash animations to step through modelling process for electrical circuits and a large data base of CAA developed on webct

Description

Introductory course on learning and using MATLAB aimed at 1st year engineering undergraduate. These were developed at the University of Sheffield and authored by J A Rossiter from The Department of Automatic Control and Systems Engineering. The files include a slightly animated power point slide (runs via web) which includes audio. Hence a little like a lecture. The source m-files mentioned are also supplied in the zip files mentioned. These m-files cover a group of topics. Read the instruction file to learn how to make 'lectures' available to students. More information for control with MATLAB is stored under the control contribution by same author and on the website http://controleducation.group.shef.ac.uk/acs211/notes_webct_quizzes_acs211.htm
