Research Of Multivariable System Identification Algorithm

With the development of the modern control system, it needs the high veracity for system model with greatness, complication and systematism of control system. The classical system identification methods have many limits and shortages, especially for multivariable system. So there is the necessity to study multivariable system identification algorithms adapting to the development of modern industrial system. Main research works of this dissertation are as following:1. Open-loop multivariable system identificationBased on the deeply study the theory and algorithms of multivariable system identification, it emphasizes on the theory and implement of subspace model identification algorithm. And based on this, it gains the recursive subspace model identification algorithm. Through the simulation experiments, it checks the validity and veracity.2. Closed-loop multivariable system identificationAims at the most of systems is closed-loop system, based on the...
