Abstract
This paper discusses various hybrid applications of a variable transport lag. A specific example, the simulation of a thermally controlled environment, is presented. In it the transport lag is due to the delay caused by having to move a mass of heated air by pump from the heating element into the environment. Various forms of heater control and delay function are presented and their effects on the system are described.
Experimental results for various forms of heater con trol and transport lag variation are presented along with a discussion of the problems involved with this type of simulation. Finally, remarks as to possible methods of improvement and extensions are made.
