This paper studies the design of an optimal relaxed causal sampler using sampled data system theory. A lifted frequency domain approach is used to obtain the existence conditions and the optimal sampler. A state space formulation of the results is also provided. The resulting optimal relaxed causal sampler is a cascade of a linear continuous time system followed by a generalized sampler and a d...
Many photometric time-domain surveys are driven by specific goals, such as searches for supernovae or transiting exoplanets, which set the cadence with which fields are re-imaged. In the case of the Palomar Transient Factory (PTF), several sub-surveys are conducted in parallel, leading to nonuniform sampling over its ∼20, 000 deg2 footprint. While the median 7.26 deg2 PTF field has been imaged ...
For a sampled-data control system, we propose to choose the time between samples to be shorter than the computational delay involved in computing the control signal, an approach we call intradelay sampling. It is shown that, utilising a parallel computing architecture, this is indeed feasible and that intra-delay sampling schemes yield better performance than their slower sampling counterparts.
This paper presents the stability analysis and control synthesis for a sampled-data control system which consists of a nonlinear plant and an output-feedback sampled-data polynomial controller connected in a closed loop. The output-feedback sampled-data polynomial controller, which can be implemented by a microcontroller or a digital computer, is proposed to stabilize the nonlinear plant. Based...
Inspired by a concrete industry problem we consider the input synthesis problem for hybrid systems: given a hybrid system that is subject to input from outside (also called disturbance or noise), find an input sequence that steers the system to the desired postcondition. In this paper we focus on sampled data systems—systems in which a digital controller interrupts a physical plant in a periodi...
