In this paper, an attempt is made to find the control law using Row by Row Decoupling Problem (RRDP) and Triangular decoupling problem (TDP) concepts. Before finding the control law, the issues on specification and methodologies are addressed in detail. Finally, the control law is presented for two input and two output system for both cases. Simulation for each category is presented in detail.
An attempt is made to design the centralized controller based on the inverted decoupling structure (CCID) for non-square (nxm) processes with multiple time delays. To avoid the Moore-Penrose pseudo-inverse of the nominal plant with multiple time delays and Maclaurin series approximation, a centralized controller is decomposed into two components using inverted decoupling structure. The two components...
In this paper a method for decoupling has been presented for a specific case of MIMO system. Falb's row by row decoupling concept is utilized for developing the control law using proportional-derivative (PD) output feedback. The solutions for integrator type and specific pole type decoupled system are presented. Necessary and sufficient condition for the existence of PD output feedback decoupling...
In this paper an attempt is made to design a dynamic state feedback based decoupler (PD compensator) for MIMO system. The condition for decoupling and mathematical expressions for the set of dynamic state feedback gain matrices (K, F and Γ) for a given decoupled system transfer function matrix is formulated. Further the robustness has been tested.
This article presents the design of Internal Model Controller (IMC) based Fractional Order Two-Degrees-of-Freedom controller with the desired bandwidth specification and the robustness of the designed controller is briefly analyzed. For the conventional IMC based PID controller, One-Degree of Freedom is sufficient to meet the desired bandwidth specification for both Servo and regulatory performances...
