The main contribution of the paper is an output-feedback application in the inertia wheel pendulum (IWP). Due to the absence of a separation principle, it is necessary to design control laws that guarantee robustness against the observer error. We present a design, which renders the system iISS with respect to the observer error and, hence, ensures robustness when the error is exponentially decaying. The advantage of our design over the observer-based backstepping scheme is that we employ nonlinear damping terms, which grow slower than those in (A toolkit for nonlinear feedback design, 1989), (Singular perturbations and input-to-state stability, 1996), and result in a "softer" control law.
For dynamical systems expressed in state-space form or for systems with non-classical damping, the reduction of the structural model into the modal co-ordinales involves complex modal analysis with complex modal co-or...

In this paper by using a controller based on a neural network and an estimator, an efficient method in A/F ratio for SI engines is presented. This combined method improves plant performance effectively and provides robustness against disturbances due to work point changing. It is shown that by combining two separate methods, a useful control strategy may be generated. Simulation results reveal the superiority of this method.
