Sensitivity Analysis of Continuous-Time Systems based on Power Spectral Density [PDF]
arXiv, 2018 Bode integrals of sensitivity and sensitivity-like functions along with complementary sensitivity and complementary sensitivity-like functions are conventionally used for describing performance limitations of a feedback control system. In this paper, we show that in the case when the disturbance is a wide sense stationary process the (complementary ...

Optimal Control for One-Qubit Quantum Sensing
Physical Review X, 2018 Quantum systems can be exquisite sensors thanks to their sensitivity to external perturbations. This same characteristic also makes them fragile to external noise. Quantum control can tackle the challenge of protecting a quantum sensor from environmental

Robustness to Modeling Errors in Risk-Sensitive Markov Decision Problems with Markov Risk Measures [PDF]
arXiv, 2022 We consider risk-sensitive Markov decision processes (MDPs), where the MDP model is influenced by a parameter which takes values in a compact metric space. We identify sufficient conditions under which small perturbations in the model parameters lead to small changes in the optimal value function and optimal policy.

Adaptive Coordination of Damping Controllers for Enhanced Power System Stability
IEEE Open Access Journal of Power and Energy, 2020 This paper introduces the concept of adaptive coordination of damping controllers for enhancing power system stability. The coordination uses phasor measurement units (PMUs) to adapt to different disturbances by selecting the switching status (on/off) of

Growth-rate dependence reveals design principles of plasmid copy number control. [PDF]
PLoS ONE, 2011 Genetic circuits in bacteria are intimately coupled to the cellular growth rate as many parameters of gene expression are growth-rate dependent. Growth-rate dependence can be particularly pronounced for genes on plasmids; therefore the native regulatory ...

Risk-Sensitive Mean-Field Type Control under Partial Observation [PDF]
arXiv, 2014 We establish a stochastic maximum principle (SMP) for control problems of partially observed diffusions of mean-field type with risk-sensitive performance functionals.

Electric field control of interaction between magnons and quantum spin defects
Physical Review Research, 2022 Hybrid systems coupling quantum spin defects (QSD) and magnons can enable unique spintronic device functionalities and probes for magnetism. Here, we add electric field control of magnon-QSD coupling to such systems by integrating ferromagnet ...

Computing Sensitivities in Evolutionary Systems: A Real-Time Reduced Order Modeling Strategy [PDF]
arXiv, 2020 We present a new methodology for computing sensitivities in evolutionary systems using a model-driven low-rank approximation. To this end, we formulate a variational principle that seeks to minimize the distance between the time derivative of the reduced approximation and sensitivity dynamics.

Quantum control with noisy fields: computational complexity vs. sensitivity to noise [PDF]
, 2013 A closed quantum system is defined as completely controllable if an arbitrary unitary transformation can be executed using the available controls. In practice, control fields are a source of unavoidable noise, which has to be suppressed to retain controllability.
