Active rotor control of helicopters is the future development direction, and active flap (AFC) one most promising technologies. However, numerical simulation an AFC challenging. It necessary to consider fidelity local flow details while dealing with complex shapes motions. Therefore, few simulations field analyses influencing parameters have been conducted. In particular, there a lack aerodynam...

In this paper, distributed parameter process systems behavior is studied in frequency domain. Based on the dominant gain concept that is developed for such studies, a method is presented to control distributed parameter process systems. By using dominant gain concept, the location of open loop zeros, resulted from the time delay parameter in the process model, were changed from the right half p...

This work addresses the general problem of resilient control of unknown stochastic linear time-invariant (LTI) systems in the presence of sensor attacks. Motivated by a vehicle cruise control application, this work considers a first order system with multiple measurements, of which a bounded subset may be corrupted. A frequency-domain-designed resilient parameter-invariant controller is introdu...

In certain manufacturing processes, product quality is characterized by spatial profiles, and such profiles are expected to meet specific shape requirements. As profile shapes are affected by process conditions, properly adjusted process variables are expected to help improve profile quality. This work aims to achieve desired shapes of profiles that are sensitive to the variation of noise facto...

This paper addresses the problem of parameter convergence in adaptive extremum seeking control design. An alternate version of the popular persistence of excitation condition is proposed for a class of nonlinear systems with parametric uncertainties. The condition is translated to an asymptotic sufficient richness condition on the reference set-point. Since the desired optimal set-point is not ...
