MATLAB LTI Viewer

The tool accepts numerator and denominator coefficient arrays for LTI systems and a sample time to define a transfer function. It supports impulse, step, and frequency domain analyses, returning both numeric data and derived metrics. Conceptually, it models the system as H(s) = N(s)/D(s) and computes poles, zeros, and gain to characterize dynamics. It enables time-domain responses and frequency responses for continuous or discrete systems, depending on Ts. This is valuable for engineers evaluating stability margins, settling times, and dominant poles, as well as academics teaching control theory and students practicing system analysis. The unique value lies in providing a readily reproducible analytical workflow that aligns with standard control theory without requiring custom MATLAB code. Core features include automatic system type detection (continuous vs discrete from Ts), calculation of poles/zeros, time responses, magnitude and phase data, and summary metrics. Use cases span model validation, design iteration, and rapid scenario comparison to support tuning and stability checks. Outputs include numeric arrays, response curves data, and a concise report of key metrics. The tool emphasizes numerical robustness, proper handling of ill conditioned systems, and clear reproducibility for verification and teaching. It is well suited for researchers and practitioners who need fast, transparent LTI analysis without bespoke programming.
