In this paper we deal with design problems of active noise control systems with a pair of loudspeakers, in order to improve the system performance achieved by a single loudspeaker presented in our previous study where advantages of robust control (sampled-data H∞ control) design have been shown by comparing to the existing adaptive control based design. Firstly, as a pair of loudspeakers, the S...

In certain types of robust control techniques, it is common having to deal with control problems where the specifications, described in the time domain, need to be translated to the frequency domain. This usually happens in techniques, such as Quantitative Feedback Theory, where the control problem is developed in the frequency domain. Therefore, not only process plants and disturbances should ...

This paper presents a Converse Lyapunov Function Theorem motivated by robust control analysis and design. Our result is based upon, but generalizes, various aspects of well-known classical theorems. In a unified and natural manner, it (1) allows arbitrary bounded time-varying parameters in the system description, (2) deals with global asymptotic stability, (3) results in smooth (infinitely diff...

The paper presents robust controller design for systems with uncertain transport delays. Robust PI controllers are designed using approach, which combines the method based on plotting the stability boundary locus in the (kp, ki)-plane with the pole-placement method. The approach enables to assure robust stability of the closed loop as well as the quality of the control response prescribed by th...

A robust control approach is developed to control robot in the task space using sliding mode by support of feedback linearization control and backstepping method, in this study. The bounds of uncertainties applied in the sliding mode control are reduced by applying feedback linearization. This provides a robust control system with a less error. The back-stepping method is used to define a linea...

The design of advanced robust control is crucial for serial robotic manipulators under various uncertainties and disturbances in case the forceful performance needs industrial applications. Therefore, this work has proposed implementation a fractional order proportional tilt integral derivative (FOPTID) controller joint space 3-DOF manipulator. been designed based on calculus concept to fulfill...

This paper surveys some signi ̄cant applications of interval analysis to robust control ̄eld. Interval analysis is specially powerful in bounding the ranges of functions while providing mathematically rigorous results. This capability is especially welcome in robust control, since a variety of analysis and design problems can be cast in the evaluation of the range of functions over intervals. To...
