This study presents a novel feedback linearization control of non-linear multi-input multi-output uncertain systems for the tracking and almost disturbance decoupling performances. The main contribution of this study is to construct a controller, under appropriate conditions, such that the resulting closed-loop system is valid for any initial condition and bounded tracking signal with the following characteristics: input-to-state stability with respect to disturbance inputs and almost disturbance decoupling. In addition, a new theorem on robust stability is proposed in this study to provide a new criterion for closed-loop stability. A typical case, which cannot be solved by any previous study on the almost disturbance decoupling problem, is proposed in this study to exploit the fact that the tracking and the almost disturbance decoupling performances can be easily achieved by the proposed approach. Finally, the proposed control law is simulated in a half-car active suspension system on which the effectiveness of the design is verified.

Due to the aging population society coming, more and more families need the in-time service of medical care for the elderly. For creating a healthy and safety living environment, this study is applied to the radio frequency identification (RFID) and the software agent technology to develop the Pervasive Health Service Grid. This framework is based on the grid architecture to provide patients health service at home environment. Furthermore, we also construct a platform with mobile mechanism to fulfill the requirements of personal health care. This study will be helpful to establish the personal medical treatment environment, and enhance the service quality of health care.
