Simulation Results

An analysis of a nonlinear control system that was used to track the natural frequency of a MEMS resonator is presented in this paper. A phase-locked loop system is used to track the natural frequency of the resonator due to fatigue of the spring element. A model for the control system is established and the system behavior is analyzed using an averaging method. The analysis provides a quantitative criterion for selecting the control gain to achieve stability. Simulation results are shown to be in agreement with the theoretical analysis. Tracking accuracy under the presence of Brownian noise and capacitive position sensing noise is also analyzed by using a variance propagation equation for the nonlinear dynamic system utilizing a first-order Taylor series approximation. The theoretically estimated resolution is also found to be in good agreement with simulation results.

In this paper, we propose a controller for a camera-based Pan-Tilt device. The approach uses the target image feature to steer the Pan-Tilt device to the target with random movement. Since these systems are often mounted on mobile equipment, energy efficiency should also be taken into account. In order to improve the control energy consumption efficiency of the Pan-Tilt system mounted with cammera, the authors use a dark objective function with optimal energy components to find controller parameters. Simulation results on the PanTilt system show that the camera can track a moving target quickly and stably and the control energy can be changed through the controller parameter according to the purpose of use.
