The Model Establishment and Simulation Analysis of Controllable Pendulum

Abstract:

Indicating vertical in moving base to establish horizontal reference is of great significance for the near-earth autonomous navigation. Existing vertical indicating device achieves the goal by using gyro stabilized platform, but the gyroscope is difficult to maintain and has drift error. This paper proposes controllable pendulum system that is a stable closed-loop control system and similar to inverted pendulum system to accomplish the purpose. This paper covers the preliminary validation of the controllable system’s ability of indicating vertical in pulse interference cases and raises the defects of system under condition of step disturbance, by establishing mathematical model, designing double output PID controller and analyzing error , which lays the foundation for follow-up study.
