Feedforward Control Concepts through Interactive Tools
(2011) 18th IFAC World Congress, 2011- Abstract
- This paper presents an interactive software tool for basic and advanced concepts of feedforward control. The ideal compensator is analyzed to show how the effects of the load disturbances are eliminated from the process output. Furthermore, it is also shown that the ideal compensator is seldom realizable, since the compensator may be non-causal, it may be unstable, it may have infinite high-frequency gain because of derivative action, and it may require a more complicated structure than what is available. The drawback of not taking the feedback controller into account during the typical open-loop feedforward design is also studied.
The proposed software tool helps to evaluate all these situations in an interactive way, enabling...
