For robust design of a product, the response surface model (RSM) of the dynamic characteristics considering many control factors and error factors was established. The formulas needed for statistical analysis were derived. The least square estimation of the model parameters was presented. A thermal expansion instrument was taken as an illustrative example. Simulation results indicate that the RSM method is better than the signal-noise ratio method proposed by Taguchi.
