Simulation research on random vibration stress of quadrotor unmanned aerial vehicles
Abstract
New types of variable frequency sinewave oscillators are introduced which bring the most desirable linear tuning laws of the forms f sub 0 proportional to Re and f sub 0 proportional to Ce into the domain of sinusoidal oscillators. Two exemplary circuits are presented and the experimental results are given which are found to be in agreement with the theory. In their various modes of operation, the proposed types of oscillators promise to provide many significant advantages in various instrumentation and measurement applications which are not possible to achieve with previously known active resistance-capacitance (RC) oscillators.
