Proportional controller design for two input two output processes

In the process control industry number of the two input two output process is substantial. The interaction between the system subcomponents makes control process difficult many times, it brings the problem of activate the system as a stabil form before the system performance anxiety as in the case of temperature and moisture must be examined at the same time in the automotive sector and the dyehouse automation. The scope of this thesis as a forward looking, the goal of solving the same problem is kept hide for multi input multi output systems, all proportional controller makes the system stable will be parameterized in particular two input two output systems offered above. During this work, terms will be evaluated in solution way such as relative gain array, diagonal dominance, centralized control and decentralized control approaches, generalized Nyquist diagrams and characteristic value curves. Control theory will be gained depth about algebraic approach, difficulties in the application and the method such as pre-filter design techniques will be specialized.
