Research on inertial stabilization platform on mobile carrier in complex environment

Abstract

The inertial stabilization platform on the mobile carrier has been widely used in military and civilian fields, such as modern satellite TV receiving and broadcasting, mobile satellite communication for vehicles and ships, as well as cash transport vehicles, public security, fire protection, disaster relief, environmental monitoring and many other industries. The platform needs the ability to isolate the effects of carrier motion, and to ensure the interception, identification and tracking of the target signal under various meteorological conditions. We choose the platform of photodetector component. It uses the electromechanical to control detector according to the instructions, automatically identifing and capturing the target. In the working process, the servo system is the key guarantee of the high performance of the platform. According to the high precision, fast response, wide frequency band and strong robust performance requirements of the system, we propose a single neuron adaptive PI+DOB (Proportional Integral+Disturbance Observer) control strategy, a method for continuous nonsingular terminal sliding mode control and a improved statistical model adaptive filtering algorithm. Through theoretical research and experimental analysis, our method improves the performance parameters based on the original system, and provides theoretical support for future researchers to develop high-precision inertial stabilization platform.
