A control and signal processing integrated circuit for the JPL-Boeing micromachined gyroscopes

A special-purpose integrated circuit that accomplishes the real-time control and filtering tasks for the JPL-Boeing micromachined gyroscopes using a flexible, low-power implementation is presented. Our exposition focuses on the integration of the circuit and a prototype sensor, the synthesis and implementation of the control filters, and the subsequent performance of the closed-loop system. Identified sensor models are also presented because the control approach and, hence, the circuit architecture, is motivated by special features of the sensor dynamics.
