摘要：It is usually possible to describe the dynamics of physical systems by a number of simultaneous linear differential equations with constant coefficients. But for many processes (like chemical plants and nuclear reactors etc) the order of the matrix may be quite large. So it would be difficult to work with these complex systems in their original form. The analysis and synthesis of such higher order systems are difficult and generally not desirable on economic and computational considerations. In such cases, it is common to study the process by approximating it to a simpler model. . For instance, the response of an airplane is quite commonly approximated by a second order transfer function. Through model order reduction, a complex higher order system can be converted to a simple lower order system. The reduced models are constructed such that all the parameters can be preserved with acceptable accuracy
