Abstract

The invention discloses a stable platform adaptive to various environments. The stable platform can detect angular rate information caused by the environment change through an MEMS gyroscope; a PID parameter of the stable platform is intelligently planned according to the angular rate information in the environment, so that the aim of freely switching a PID algorithm under any environment is achieved, and the stabilization precision of the platform can be further improved. An inertial measurement combination comprises a three-axis gyroscope, a three-axis accelerometer, a three-axis magnetometer, a main control chip and an attitude algorithm, and outputs a course angle, a roll angle and a pitching angle. The attitude algorithm adopts a quaternion attitude algorithm, a calculated attitude is fed back to a driving motor, and the intelligently planned PID algorithm is used for stably controlling an attitude, so that the stable effect of the platform is achieved.

Description

technical field [0001] The invention relates to the technical field of automation and instrumentation, in particular to a stable platform adaptable to work in various environments. Background technique [0002] At this stage, during the transportation of the wounded in the field and the rescue of the seriously wounded, secondary injuries to the wounded often occur due to bumps and vibrations on the road. The transportation of hazardous chemicals and fragile goods also faces the hazards and economic losses caused by uneven road surface, bumps and vibrations. Solving vibration isolation and anti-shake will become the core of the problem. In response to this problem, it is planned to apply the stable platform to scenarios such as rescue of the wounded, transportation of dangerous and fragile goods, etc., to isolate the environment from vibration, which will more effectively ensure the safety of people's lives and property. [0003] In addition, how to adapt the stable platfor...
