In this paper, we conduct research on the large precision instrument error correction model under the perspectives of stability and robustness. It is one of the effective methods to improve the instruments accuracy using error correction technology, but at present, a lot of error correction is limited to the system error modification, only a small number of the instruments to an error in the dynamic error correction timely, device on the instrument precision sensors, apparently complicate the instrument structure. To fully system error correction that will affect the precision of instrument mainly random error. Instrument is the main task of error correction is to use a certain method to compensate separable instruments each component part of a deterministic system error, so the key problems of error correction as is the requirement of equipment structure stability is good, with this to ensure that the instrument error of the uncertainty, so that the fundamental flaw. Under this basis, this paper proposes the novel countermeasure of the issues that is innovative
