The temperature in a laboratory model of a house is controlled using hot
water from a constant temperature hot water supply tank. The measured feedback
signals are received from temperature sensors, liquid flow rate sensors.
A personal computer is used to control solenoid valves regulating the hot
water flow. The program, written in "C" language, uses a PCL812P input/output
card to implement the control algorithm after entering the desired room
temperature and time of day per room. MATLAB or TUTSIM system simulation
is compared with actual system results.
