The following resources come from the 2009/10 BEng in Electrical Engineering (course number 2ELE0066) from the University of Hertfordshire. All the mini projects are designed as level two modules of the undergraduate programmes. The objectives of this module are to demonstrate within an industrial environment: • To use Matlab® (Simulink®) • To implement an appropriate analogue computer for modelling dynamic systems. A DC motor model, in specific prototyping stages, is more appropriate to use than the actual DC motor. This project aimed to design and implement a DC motor model by using a simulation package (CAD) such as Matlab and implement the equivalent electronic hardware platform.

16. To Do list for today You will need to be familiar with the topics above for future session of the mini project. Make sure you are familiar with topics 5, 6 and 7 as you will not have time to do them during the mini project future sessions. Topics to Read/Practice Progress 1 Review the unity feedback control theory 2 Find the help file for the SISO tool 3 Enter a plant with a pole at -1 in the SISO tool 4 Design a compensator that results in a settling time < 1msec. 5 Enter a second order plant with a pole at -1 +10j. 6 Design a compensator that results in a settling time of <1usec. Is this possible? 7 Design the Simulink setup up for the above two cases. 8 Find the general transfer function of the PI compensator.
