In this paper a new performance index, based on a periodic evaluation of the integral of the absolute error, is proposed for monitoring switching DC-DC converters. Parameter variations or operating condition modifications can be easily estimated using a relay closed loop tests without stopping the process. An interesting practical application of such method is the retuning of standard controllers in case of variation of nominal conditions, by using scale factors applied to controller coefficients.

Abstract
In this paper a new performance index, based on a periodic evaluation of the integral of the absolute error, is proposed for monitoring switching DC-DC converters. Parameter variations or operating condition modifications can be easily estimated using a relay closed loop tests without stopping the process. An interesting practical application of such method is the retuning of standard controllers in case of variation of nominal conditions, by using scale factors applied to controller coefficients.File in questo prodotto:
