Strapdown Inertial Navigation

This paper investigated the vibration control based on intelligent materials for strapdown inertial navigation system (SINS) from theoretical analysis to simulation verification. At first, significance of vibration control in SINS and the disadvantages of the traditional vibration control methods were set forth. Then, intelligent material and structure were introduced to improve the situation. A method of combining active and passive vibration control based on piezoelectric ceramic had been put forward. Through modeling and designing PID and fuzzy PID controller separately, the simulation results show that both the model and the control methods are effective. Finally, its effectiveness and the further researched required to be done were summarized.

Derivative Control

The piezoelectric materials have the positive and inverse piezoelectric effects. The piezoelectric elements can be served as actuators and sensors. The piezoelectric elements are adopted to control the vibration of autobody thin-wall structure. The proportional control, proportional-derivative control and independent modal space control based on LQR (Linear Quadratic Regulator) are simulated by using finite element method. The piezoelectric patched autobody thin-wall structure is simplified to a square plate with peripheral clamped boundary. The finite element model is established. The central node displacement is monitored as a control variable in these control methods. Central patched plate and surrounding patched plate are analyzed under the three control methods. The effectiveness of vibration control is obtained. Compared with proportional control, the proportional-derivative control has advantage of oscillation suppression at the beginning vibration control and has more obvious vibration control effectiveness. Compared with the above two control methods, the independent modal space control based on LQR has a better stability and vibration suppression effectiveness.
