Achieving modulated oscillations by feedback control.

In this paper, we develop an approach to achieve either frequency or amplitude modulation of an oscillator merely through feedback control. We present and implement a unified theory of our approach for any finite-dimensional continuous dynamical system that exhibits oscillatory behavior. The approach is illustrated not only for the normal forms of dynamical systems but also for representative b...

Oscillations in Nonlinear Pulse-modulated Control Systems

Periodical modes in nonlinear control systems with pulse-width and pulse-frequency modulation are considered. The existence of a fixed point for the shift operator along system’s trajectories is frequently used to establish the existence of a periodical mode. However, this method often fails for pulse modulated systems due to discontinuity of the shift operator. The new geometrical approach is ...

Control of noise-induced oscillations by delayed feedback

We propose a method to control noise-induced motion, based on using delayed feedback in the form of the difference between the delayed and the current states of the system. The method is applied to two different types of systems, namely, a selfoscillator near Andronov-Hopf bifurcation and a threshold system. In both cases we demonstrate that by variation of time delay one can effectively contro...

Active vibration control of smart building frames by feedback controllers

In this paper the active vibration control of a four-story shear frame instrumented with piezoelectric actuators is presented. The piezoelectric actuators are hosted on the columns in two manners and the produced controlling forces by actuators are considered in the equation of motion. The smart structure modeling and control design is carried out using MATLAB software in state space form. Subs...

Oscillations by the p53-Mdm2 feedback loop.

The p53 network is perhaps the most important pathway involved in preventing the initiation of cancer, p53 levels and activity are upregulated in response to various stresses including DNA damage, hypoxia, and oncogene activation. Active p53 initiates different transcriptional programs that result in cell cycle arrest, cellular senescence or apoptosis. p53 also activates the transcription of Md...
