This paper studies quantized and delayed state-feedback control of linear systems. We consider two types of quantization: quantized feedback and quantized state. The quantizer may be either unconstrained or saturated with a given quantization error bound. The delay is supposed to be time-varying and bounded. The controller is designed with the following property: all the states of the closed-lo...

The response of particle density to a dilation of a periodic potential in an insulator, with or without a fixed background potential or a magnetic field, is shown to be quantized. A similar phenomenon occurs in a quantum Hall system, where the derivative of the electron density with respect to the magnetic field is quantized in units of e/h, the inverse flux quantum. A number of other interesti...

[Abstract] Quantization problem in digital control system have attracted more and more attention in these years. Normally, a quantized variable is regarded as a perturbed copy of the unquantized variable in the research of quantization effect, but this model has shown many obvious disadvantages in control system analysis and design process. In this paper, we give a new model for quantization ba...

This paper studies the quantized H∞ filtering problem for continuous-time systems with a type of dynamic quantizers, which are conjuncted with static quantizers via dynamic scalings. The static quantizer ranges are fully considered here for practical transmission channels requirements. A quantized H∞ filter design strategy is proposed, where a convex optimization method is developed to minimize...

Quantized vortices are key features of quantum fluids such as superfluid helium and Bose-Einstein condensates. The reconnection of quantized vortices and subsequent emission of Kelvin waves along the vortices are thought to be central to dissipation in such systems. By visualizing the motion of submicron particles dispersed in superfluid (4)He, we have directly observed the emission of Kelvin w...

A quantized feedback system is a control system in which finite-level quantization of signal values is involved in the feedback loop. Quantized feedback is found in many engineering systems including mechanical systems and networked systems because multilevel-valued devices such as A/D (Analog-toDigital) converters, on/off switching actuators, and digital communication networks are widely used ...

This paper introduces identification algorithms for finite impulse response systems under quantized output observations and general quantized inputs. While asymptotically efficient algorithms for quantized identification under periodic inputs are available, their counterpart under general inputs has encountered technical difficulties and evaded satisfactory resolutions. Under quantized inputs, ...

This paper is focused on the dynamic output feedback control of sampled-data system with actuator saturation using quantized measurements. The output signals are quantized before they are transmitted to dynamic output-feedback controller. An augmented system is constructed through a closed-loop system, which is a model with an interval time-varying delay and nonlinear items. Using discontinuous...
