One of the basic problems in the field of fuzzy control is to find out how many rules are necessary to get a good fuzzy controller.To solve the problem,the error estimates for multivariate Lagrangian interpolates are given.From this,the upper bound of the rule number for a good multi-input fuzzy controller can be found out.The errors for a fuzzy controller to approximately precise control can be obtained after determining fuzzy rule base.The efficiency of the method is verified by simulation results.
