基于Jacobian矩阵的牛顿迭代法惠斯通电桥调零
Wheatstone Bridge Zeroing Based on Jacobian Matrix Newton-Iterative
摘要
Abstract
In order to achieve high-g acceleration during the firing of the air cannon triggering the system to collect, the piezoresistive high-g acceleration needs to be precisely zeroed, and the traditional zero-error through the sliding rheostat is greater, This paper proposes a mathematical model by establishing Wheatstone bridge and analyzing nonlinear equations, so as to simplify Jacobian matrix. The algorithm has good local convergence, can achieve high-precision zero MEMS sensor bridge, which is convenient for accurately capturing the overload signal emitted by the air cannon. Numerical simulation and air gun experiments show that with this scheme, the life cycle of the missile is prolonged, and the firing signal of the air cannon can be captured.关键词
