A new reduced control design based on the theory of wave domain control

The work in this paper is based on the theory discussed previously by Wang et al. (1994). The main idea is to establish a transformation, which changes the original system into an image system, in which the control force is designed in the context of wave domain control and wave control, so that the number of degrees of freedom in the undisturbed state of the image system can be reduced. The design of control in the original system can be derived by inverse transformation. This method, compared with the previous one, is more general and is easy to apply.
