Sensitivity Analysis for Time Domain Response of Transmission Lines Based on the Precise Integration Method

Since the sensitivity analysis method for time domain response of transmission lines based on the frequency domain method is difficult to handle with the sensitivity problem of transient response of transmission lines, a novel method based on the precise computation method is described for the sensitivity analysis for time domain response of transmission lines in this paper. By the difference divergence of space of telegraph equations in time domain to construct the first-order differential equation of transient response of transmission lines and sensitivity of transient response of transmission lines to time, it uses precise integration method to analyze the sensitivity of response in time domain directly. It's a semi-analytical method in time domain which is simple, accurate and stable. It can handle with the sensitivity of time domain response of transmission lines with arbitrary terminal loads, boundary conditions and transmitted signals. Finally, the application example proves the correctness of method in this paper.
