This paper presents a robust controller design methodology for a class of linear uncertain multivariable systems with hard time-domain constraints on their outputs and control signals in response to step disturbance inputs. In this approach, the m×m MIMO system is replaced by m2 SISO systems and then, using the QFT technique, desirable controllers are synthesized. The final controller will be d...

Obtain greater throughput, reduced variability, and increased profitability by using DeltaVTM Predict and DeltaVTM PredictPro to implement multivariable model predictive control strategies. DeltaV Predict and PredictPro use the power of dynamic matrix control to easily address process interaction and difficult dynamics. Since DeltaV Predict and PredictPro are fully embedded in the DeltaV system...

Quadrotor control has been noted for its trouble as the consequence of the high maneuverability, system nonlinearity and strongly coupled multivariable. This paper deals with the simulation depend on proposed controller of a quadrotor that can overcome this trouble. The mathematical model of quadrotor is determined using a Newton-Euler formulation. Fractional Order Proportional Integral Derivat...

The process establishing clearly described. simulation performed by MATLAB software. results have sho...

Abstract– After a disturbance occurrence, fast damping of power oscillations is essential to reduce the risk of instability and thus increase the power transfer capacity of transmission systems. Recently, the Static Series Synchronous Compensator (SSSC) has justified its ability to improve power oscillation damping. Due to substantial interactions among the SSSC damping control loops and the po...

The proton exchange membrane fuel cell gas control has been one key point in management systems. complexity and coupling of the air system make it difficult to achieve precise intake adjustment. In this paper, an accurate joint method for flow pressure regulation is proposed. nonlinear mathematical model developed describe output characteristic state change. Based on this, feedback linearizatio...

An internal multimodel control designed for nonlinear multivariable systems, is proposed in this paper. This approach is based on the multi-modeling of nonlinear systems and the realization of a specific inversion of each model. A comparative study is presented between two structures of the internal multimodel control. The first one is based on switching models and the second on residues techni...
