Wave-Based Control - Implementation and Comparisons

Success in controlling flexible system is constrained by unavoidable practical limitations, such as actuator dynamics, exactness of system parameter modeling, and the accuracy of the system feedback available. Ultimately the practicality of implementing a control scheme will be determined by the robustness of the scheme to such non-ideal behavior, and by its ease of implementation. Wave-based control is presented as performing well on all these issues. Comparisons with other schemes for controlling flexible systems are made which show that it is not only relatively easy to implement but is also capable of achieving very fast responses.
