This work considers the problem of quantum gate generation for controllable quantum systems with drift. It is assumed that an approximate solution called seed is pre-computed by some known algorithm. This work presents a method, called Fixed-Point Al

Geração Rápida e Virtualmente Exata de Portas Quânticas Via Métodos Iterativos do Tipo Lyapunov

Autor: Paulo Sergio Pereira da Silva, Pierre Rouchon, Hector Bessa Silveira

Publikováno v: Proceedings XXII Congresso Brasileiro de Automática.

O problema de geracao de portas quânticas e um problema de controle em malha aberta. Por um lado, o controle otimo gera solucoes rapidas mas com uma complexidade computacional imensa, inaceitavel para sistemas da ordem elevada, por outro lado a esta

Autor: Nestor Roqueiro, Leandro Yoshio Morita, Hector Bessa Silveira

Publikováno v: VSS

This works treats the control problem of tracking the steering angle and the longitudinal velocity desired by the driver of a tilting 3-wheeled vehicle while keeping its tilt angle within a safety margin, so as to achieve safe and easy driving in clo

A TRIANGULAR FORM FOR FLAT NONLINEAR SYSTEMS WITH TWO CONTROLS AND FIVE OR LESS STATES

Autor: Paulo Sergio Pereira da Silva, Hector Bessa Silveira

Publikováno v: IFAC Proceedings Volumes. 40:118-123

This paper shows that, for flat affine time-invariant continuous-time nonlinear systems with two controls and five or less state variables, there exists a smooth change of coordinates and a time-invariant regular static state feedback such that the s
