T he con- vergence of the algorithm is researched. T he theory gist to select learning rate is provided by the conver- gence theorem. To validate the validity of the algorithm, the simulating example of the error compensation on sensor w as given. T he result shows that the error compensation approach on sensors using the neural netw or algorithm with orthonormal basis functions has a high precision of error compensation. There- fore, the method of the error compensation presented in the paper is effective.
