This paper presents a ubiquitous thermal comfort preference learning study in a noisy environment. We introduce Gaussian Process models into this field and show they are ideal, allowing rejection of outliers, deadband samples, and produce excellent estimates of a users preference function. In addition, informative combinations of users preferences becomes possible, some of which demonstrate wel...

This paper investigates the stability as well as communication properties of sampleddata control and two event-triggered control schemes: deadband control and model-based eventtriggered control. After proposing a uniform representation, these schemes are compared by deriving approximation error bounds with respect to the behavior of the continuous-time statefeedback loop and by specifying lower...

This paper discusses the design, fabrication, and test of a CMOS active clamp circuit. The active clamp is a linear voltage regulator, with a voltage deadband to allow for voltage ripple, that is designed to operate in parallel with a switchmode voltage regulator. Its specific function is to sink or source large transient currents to microprocessor loads, thus allowing operation with very small...

A comprehensive digital computer model of the two-area interconnected power system including the governor deadband non-linearity, steam reheat constraints and the boiler dynamics is developed. The improvement in AGC with the addition of a small capacity Superconducting Magnetic Energy Storage (SMES) unit is studied. Time domain simulations are used to study the performance of the power system a...

In this paper, a closed-loop switching function for on-off thruster firings is proposed to provide good attitude control performance in the presence of modeling errors for single-axis slew maneuver of a rigid spacecraft and to eliminate double-sided thruster firings. The size of a single-sided deadband in the switching function provides the capability of a tradeoff between maneuver time and fue...

Current haptic (force feedback) telepresence systems operated over a communication network as, e.g. the Internet, require high packet rates for the transmission of the command and sensor signals. We propose a novel approach to reduce the network traffic by means of deadband control. Data packets are only sent if the sampled signal changes more than a given threshold value. Passivity based estim...
