In our previous paper (1999), this was treated under the certainty equivalence assumption. The control design produces a finite dimensional measurement feedback controller which is computable online provided certain conditions are met. In this paper, we do not use the certainty equivalence theory. Instead, we use the more general theory given by Helton et al. (1999). We design a controller for globally stabilizable linear systems with actuator nonlinearities which is finite dimensional and computable but does not require the onerous certainty equivalence assumption.","PeriodicalId":137513,"journal":{"name":"Proceedings of the 38th IEEE Conference on Decision and Control (Cat.

This paper focuses on the issue of integrability. The main import of the paper is to demonstrate that the classical theory of tops, initiated by L. Lagrange, J. Louiville and S. Kowalewski (1889), extends to holomorphic Hamiltonian systems on complex Lie groups SO/sub n/(C), and that complex Lie groups are a natural setting for proper understanding of the basic phenomena.","PeriodicalId":137513,"journal":{"name":"Proceedings of the 38th IEEE Conference on Decision and Control (Cat.

In order to overcome this problem, we propose a novel control method, called a prediction-based feedback control, for discrete-time chaotic systems. Moreover, we give necessary and sufficient conditions for exponential stabilization of fixed points by the proposed method.","PeriodicalId":137513,"journal":{"name":"Proceedings of the 38th IEEE Conference on Decision and Control (Cat.

A notion of robust stability, referred to as bi-quadratic stability, which is based on a Lyapunov function that depends quadratically on the uncertain parameters is proposed. LMI based sufficient conditions for bi-quadratic stability of continuous- and discrete-time systems are developed. The proposed stability analysis methods have the advantage that they can be used for solving problems of robust control synthesis, including robust stabilization, robust H/sub 2/ control, and robust H/sub /spl infin// control.","PeriodicalId":137513,"journal":{"name":"Proceedings of the 38th IEEE Conference on Decision and Control (Cat.
