SYMBOLIC ALGEBRA AND PHYSICAL-MODEL-BASED CONTROL

In order to achieve the best possible control of a particular system, it is clear that as much information about the system as possible shou ld be used when designing the controller. This leads to a controller s pecifically tailored to the system being controlled. Unfortunately thi s is expensive in terms of design time and expertise and a number of a pproaches have been suggested to overcome this problem. The approach t aken by physical-model-based control is to model the system in a gener ic manner and then automatically design the controller based on this m odel. This process requires symbolic algebra to enable the controller to be designed.
