- Abstract:
- The paper presents a new approach to design of adaptive measurement systems (AMS) for top-precision wide range measurement of physical excitations (acceleration, pressure, etc.). AMS include the array of compensatory sensors adaptively adjusted using the analog-digital compensating circuits and digital data processing unit (DPU). The measurement of an input excitation is realized as iterative improvement of its estimates using data consequently delivered to DPU by the sensors with growing sensitivities. The principles of the system operation and optimal algorithm for the AMS control and estimation of the input excitation are described. The particularity of the AMS operation is elimination of saturation of the sensors at the confidence level provided by the proper choice of their sensitivities.
