—In this paper, a multimachine power system is first represented as the generalized Hamiltonian control system with dissipation. Then, a decentralized saturated steam valving and ex-citation controller, which is staticly measurable, is proposed based on the Hamiltonian function method. Last, an example of three-machine power system is discussed in detail.
—This note deals with chained form systems with strongly nonlinear unmodeled dynamics and external disturbances. The objective is to design a robust nonlinear state feedback law such that the closed-loop system is globally-exponentially stable. We propose a novel switching control strategy involving the use of input/state scaling and integrator(More)
— We propose a control approach to transfer the population between selected quantum states in the non-Markovian open quantum system. This transfers, assisted by single qubit phase shift operations can generate universal logic gates for quantum computing. We find that the occupation probability behaves differently for different environmental conditions, such(More)
