Quantum control concerns driving quantum systems to the desired properties or states. This objective is hindered by the non-deterministic nature of quantum systems and the symmetric topology of the quantum state space. This paper introduces a coupling Lyapunov functions approach to counter for the stochastic nature of quantum measurements and break the symmetric topology of resulting filter state...
Integrated servo-mechanical design is commonly solved using numerical methods. In this paper, allowable regions for the redesigned open loop Nyquist plot are derived based on performance and chance-constrained robust stability specifications, considering high-frequency reshaping of the mechanical plant based on a low-order controller. Our simulation results on the Pb-Zr-Ti active suspension in a commercial...
Integrated servo-mechanical design for achieving control specifications and robust stabilization of high-performance mechatronics is generally a nonlinear and nonconvex optimization problem. In this paper, a convex separable parametrization is proposed for simultaneous finite frequency redesign of the mechanical plant and controller considering performance specifications and plant parameter distributions...
To make full use of the amazing characteristics of quantum states, control of open quantum systems is of great significance in practical applications. This paper studies a more practical control problem where the decoherence parameter is not known exactly. The problem is considered in two phases. First, the unknown decoherence strength is estimated based on continuous measurements and an appropriately...
