Welcome to the subject Control Systems III (Practical) (CSYPRA3) at UNISA. This tutorial letter serves as a guideline to this subject. It provides you with general administrative information as well as specific information about the subject. Read it carefully and keep it safe for future reference. We trust that you will enjoy this course.

successfully implemented in numerous practical systems and processes—for example, in controlling temperature, pressure, and fluid level; in electrical energy plants; in industrial plants producing paper, cement, steel, sugar, plastics, clothes, and food; in nuclear and chemical reactors; in ground, sea, and air transportation systems; and in robotics, space applications, farming, biotechnology, and medicine.

This practical subject (CSYPRA3) aims to provide students with opportunities to practice these theoretical results by modelling, designing and analysis practical systems that are widely used in industry.

Your Lecturer for Control Systems III is Prof S Du. He can be contacted at the following number for any theoretical questions:

this device is connected to the control valve in order to control the inflow rate iq . When q increases (decreases), o

then y decreases (increases) and the analog device opens (closes) the control valve, thus increasing (decreasing)

The differential equation describing the system is determined as follows. The continuity law of fluids states that the

amount of liquid which enters the container minus the amount of liquid which leaves the container is equal to the

are the differentials of time and height, respectively. If the load valve is open (which means that qo>0 ), then the

continuity law of fluids gives

Substitute relation (3) into Eq. (2) to yield

ANNEXURE C

All students must have their own practical guide and components.

Every student must do his own practical, however students are allowed to receive help in a constructive manner.

Students need to take every safety precaution (especially where the experiment involves 220-V and 380-V alternating current). UNISA cannot be held responsible for any damage to equipment or harm to any person. In cases where the student is in doubt about any safety aspect, contact Unisa for assistance.
