Measurement of Time Constant of First Order System by Numerical Integration
Abstract:Unit sensitivity must be ensured to estimate the natural parameter of the first order system which is time constant by the classical method. A new method based on numerical integration is discussed to estimate the natural parameters of the first order system. By comparing with the existing measurement methods, it shows that the method disscussed can achieve higher eatimating accuracy under high noise level. Calculation results prove the effectiveness of the method.
Keywords: measurement first order system time constant numerical integration
