Quadratic-exponential coherent feedback control of linear quantum stochastic systems
Igor G. Vladimirov, Ian R. Petersen
This paper considers a risk-sensitive optimal control problem for a field-mediated interconnection of a quantum plant with a coherent (measurement-free) quantum controller. The pla…
Two-step feedback preparation of entanglement for qubit systems with time delay
Yanan Liu, Daoyi Dong, Sen Kuang +2
Quantum entanglement plays a fundamental role in quantum computation and quantum communication. Feedback control has been widely used in stochastic quantum systems to generate give…
Fault-tolerant control for optical parametric oscillators with pumping fluctuations
Yanan Liu, Daoyi Dong, Ian R. Petersen +1
Optical Parametric Oscillators (OPOs) have wide applications in quantum optics for generating squeezed states and developing advanced technologies. When the phase or/and the amplit…
Strictly negative imaginary state feedback control for relative degree two systems
James Dannatt, Ian R. Petersen
In this paper, we present a strictly negative imaginary state feedback control methodology for relative degree two negative imaginary systems such as flexible structures with collo…
A Coherent LQG approach to Quantum Equalization
Rebbecca TY Thien, Shanon L. Vuglar, Ian R. Petersen
We propose a method to design a suboptimal, coherent quantum LQG controller to solve a quantum equalization problem. Our method involves reformulating the problem as a control prob…
Nonlinear Negative Imaginary Systems with Switching
Kanghong Shi, Ian R. Petersen, Igor G. Vladimirov
In this paper, we extend nonlinear negative imaginary (NI) systems theory to switched systems. Switched nonlinear NI systems and switched nonlinear output strictly negative imagina…
