“…Among these the prediction errors (PE) method and the instrument variable (IV) method are quite popular for both simulated and real data. The methods for CT model identification have been applied in various forms such as state vector filtering (SVF), instrumental-variable (IV), generalized Poisson moment functional (GPMF), subspace state-space estimation (N4SID), and simplified refined instrumental variable method for continuous-time (SRIVC). ,,− The merits and demerits of these methods have been studied in detail by Ljung et al In the present work for identifying the data driven models, various CT model identification algorithms like SRIVC, SVF, IV, GPFM, and N4SID of CONTSID toolbox , and SYSID toolbox of MATLAB have been used.…”
