Abstract

On the basis of decoupling algorithm

the error characteristics and fault-tolerance strategy of a parallel type six-axis accelerometer were researched. By introducing an aided angular velocity and using quaternion to describe rotation parameters in a four-dimensional space

two explicit recursive formulas with simple forms were obtained

and six-axis accelerations were entirely decoupled. By analyzing the decoupling mechanism

three kinds of error sources affecting the decoupling precision were obtained

and the reasons that cause the error were analyzed. By establishing the mapping relations between the error of aided angular velocity

source errors and output errors

the analytical expressions of the basic error equations were derived

and then the influence rules of error components were revealed. The verification experiment shows that the mathematical results are well consistent with the simulation ones in ADAMS

and the relative error between them is acceptable. Three force coordination equations were derived by establishing the hidden deformation compatibility conditions of elastomeric topological configuration

and then a fault-tolerant processing scheme was proposed to solve 93 combined failures. Experimental results indicate that the maximum relative error is 8.5% after using the new algorithm to decouple the six-axis acceleration of the systems with partial failures

which meets the accuracy requirements. Above results verify that the influence rules of errors and the scheme of fault-tolerant processing are both correct and feasible

and also demonstrate that the parallel type six-axis accelerometer has some level of robustness.
