Description

technical field [0001] The invention belongs to the field of control systems, and in particular relates to an improvement of an aircraft attitude control system. Background technique [0002] MEMS inertial sensors have the advantages of small size, light weight, low power consumption, fast startup, low cost and high reliability. Therefore, the miniaturized attitude measurement system based on MEMS sensors has become the first choice for aerial photography of unmanned aerial vehicles. Accurate and real-time acquisition of the attitude angle of the aircraft in the air is the key to determining the control accuracy and system stability. However, in the aerial survey system composed of low-cost MEMS inertial sensors, due to the influence of temperature, mechanical vibration and other factors . There is a large static drift error, and long-time integration will cause the divergence of the attitude angle, so it is not suitable for the determination of the long-term attitude angle...
