Some researchers argue that task switching involves task-set reconfiguration--that is, changing the existing task set to perform a different task. Although this idea is intriguing, it is often unclear what is reconfigured and which processes are involved in reconfiguration. We addressed these issues by defining task sets, identifying differences between them, and obtaining evidence that was dia...

Asymmetric monotonic switching scheme is proposed for a low power successive approximation register (SAR) analogue-to-digital converter (ADC). The proposed switching procedure consumes no energy from reference voltage for the first 3 MSB (most significant bit) conversion using unequal initial DAC setting and asymmetric binary search algorithm. After 3 MSB conversions, DAC switching utilizes a c...

This paper deals with the multiband hysteresis control technique which tracks the desired reference current and provide desired voltage and current waveform with less distortion for grid connected systems. Cascaded H bridge multilevel inverter is used in high power and medium power applications. Multiband tracks the desired reference current and is used for evaluating the performance of multile...

This paper is devoted to the study of multi-agent consensus with a time-varying reference state in directed networks with both switching topology and constant time delay. Stability analysis is performed based on a proposed Lyapunov–Krasovskii function. Sufficient conditions based on linear matrix inequalities (LMIs) are given to guarantee multi-agent consensus on a time-vary reference state und...

-In the time optimal control problem, it is important to select a switching point accurately in order to improve tracking speed performance. However, the accurate selection of the switching point is not an easy task because of the damping coefficient variations and modeling uncertainties in actual systems. To relieve the difficulty and inconvenience of this task, adaptive model-following contro...

A low-power fully-integrated type-2 4-order 1.7GHz CMOS frequency synthesizer for DCS-1800 application is designed and simulated in a 0.25μm process technology. The frequency switching is achieved using a novel architecture exploiting a direct digital synthesis (DDS) device as the frequency reference. The new topology significantly lowers the undesired sideband power due to divider ratio switch...

A control methodology for asynchronous sequential machines is addressed in this paper. The considered machine consists of a number of input/state asynchronous machines, termed submachines, between which asynchronous switching is conducted by the switching signal. The control objective is to design a corrective controller so that the stable-state behavior of the closed-loop system can mimic a re...
