Accepting the challenge to state an approximate model of such system, both system analysts and control engineers, headed towards the model order reduction. Continuing the same, this paper revisits few noteworthy estimation techniques for simplification of discrete-time interval system. In particular, denominator is derived through reciprocal algorithm and numerator by two varied algorithms. The proposed algorithms are validated with examples from literatures and real-time test systems via assessment of error computation. Limitation encountered during the course is also taken into count.

For reduction of unstable system, a system decomposition algorithm is given to decompose the unstable system in to completely stable and completely unstable parts and then reduction of stable part is carried out and finally the subsystem addition of reduced stable part and already separated unstable part is done to get the final simplified model. The proposed algorithm is illustrated with an example.
