this paper presents a novel control approach used in shunt active power filter based on variable structure control combined with random pwm technique (rvsc) that provides robust, fast, and more favorable performance for active power filter. this control strategy is compared with two other strategies to show the effectiveness of the introduced methods; pulse width modulated proportional-integral...

There are numerous ways to control objects in the Stokes regime, with microscale examples ranging from use of optical tweezers application external magnetic fields. In contrast, there relatively few explorations theoretical controllability, which investigate whether or not refined and precise is indeed possible a given system. this work, seeking highlight utility broad applicability such rigoro...

An adaptive control system using extremum-seeking optimization is developed to suppress subsonic cavity flow oscillations. The overall control system is developed by following two steps. First, a simple linear control law which uses measurements of wall pressure fluctuations at two different locations in the cavity is developed, and the effect on the magnitude of the limit cycle produced by tun...

The chapter addresses bifurcations of limit cycles for a general class of nonlinear control systems depending on parameters. A set of simple approximate analytical conditions characterizing all generic limit cycle bifurcations is determined via a first order harmonic balance analysis in a suitable frequency band. Moreover, due to the existing connection between limit cycle bifurcations and rout...

The Cell Transmission Model (CTM) has been widely used to design variable speed limit (VSL) controllers. Since the CTM is an idealization of actual traffic flow, issue robustness VSL with respect uncertainties such as disturbances due modeling and measurement errors important problem. In this paper, we modify include a constant disturbance term that unknown could change over time. stability pro...
