摘要

Based on drawback analysis of infinite impact response differentiator design using basic quadratic program method, a kind of infinite-impact-response differentiator design algorithm based on iterate quadratic program for sensor has been suggested in this paper. We has solved the problems of stability and cost function, which can reduce the design error effectively and improve the performance of differentiator, so the method is perfect and credible. By many examples, the algorithm has been tested successfully.
