Robust Multivariable Control of Multi-Axis Electrodynamic Shaking System Using .MU.-synthesis

Robust Control of Multi-axis Shaking System Using Μ-synthesis

The application of the two-degree-of-freedom (2DOF) control to the electrodynamic multi-axis shaking system that is not permitted to employ the iteration control method is presented. A transformation matrix is used to remove a redundancy. The redundancy arises from the fact that the 6DOF shaking table is composed of 8-shakers. Furthermore, the influences of the specimen and the crosscoupling te...

Robust Acceleration Control of Electrodynamic Shaker Using Mu-Synthesis

This paper presents an acceleration control of an electrodynamic shaker that cannot employ the iteration control method freely. There are considerable points in the design phase of the acceleration controller. The transfer functions using the acceleration controlled variable have zero at the origin and two crossover frequencies. It is not easy to design the acceleration controller by using the ...

single-step synthesis of multi-component spirobarbiturates using ionic liquids and synthesis of substituted pyridine filled with catalysts supported on solid substrate

in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...

Turbofan engine control design using robust multivariable control technologies

A unified robust multivariable approach to propulsion control design has recently been developed at National Aeronautics and Space Administration (NASA) Glenn Research Center (GRC). The critical elements of this unified approach are 1) a robust H-infinity control synthesis formulation; 2) a simplified controller scheduling scheme; and 3) a new approach to the synthesis of integrator windup prot...
