This paper deals with multilayer and fine thermal control of an optical reference cavity for space applications. The cavity, made of ultralow-expansion glass, must be kept close to the zero-expansion temperature (ZET) of the glass (near room temperat

Pendulum tilt, with respect to local gravity, is affected by the tilt and lateral acceleration of the supporting structure. A differential pendulum, such as the Nanobalance thrust-stand, would be immune only in the ideal case of perfectly balanced pe

The paper describes the attitude control system of a low lift-to-drag biconic atmospheric entry capsule based on the Embedded Model Control methodology. The control structure derives from the development of the attitude dynamics and kinematics writte

This paper presents a solution of the translational control for a biconic atmospheric entry capsule using the bank angle as a command. The control algorithm is separated into path planning and reference-path tracking. The path-planning algorithm comp

A method is provided for avoiding heater saturation-to-zero in the design of automatic temperature regulators where both thermoelectric coolers (TEC) and heaters are used. The analysis is developed around a lumped parameter thermal model and the resu

The paper deals with the uncertainty of differential measurements, obtained from the subtraction of a pair of absolute measurements. It is shown that if the same sensor is used to perform both measurements, a model of the sensor will reveal a correla
