Energy feedback used for oscillators control

Popis výsledku v původním jazyce

There are many types of oscillators and many different circuit configurations that produce oscillations. Some oscillators produce sinusoidal signals,and others produce nonsinusoidal signals. Nonsinusoidal oscillators, such as pulse and ramp (or sawtooth) oscillators, find use in timing and control applications. Pulse oscillators are commonly found in digital-systems clocks, and ramp oscillators are found in the horizontal sweep circuit of oscilloscopes and television sets. Sinusoidal oscillators are used in many applications, for example, in consumer electronic equipment (such as radios, TVs, and VCRs), in test equipment (such as network analyzers and signal generators), and in wireless systems. There are two widely used methods of oscillator amplitude control. In the first method, the oscillator active element has a nonlinear characteristic of the limiting type. In the second method the oscillator active element has linear control of gain. In this paper a new method of control based on state energy concept is proposed. It will show that system controlled by a linear controller with energy feedback can generate different types of signals. Depending onparameters of the controller the generated output signal can be sinusoidal, nonsinusoidal, or even chaotic. A new chaotic attractor was found by means of state energy feedback.
