为了检测旋转载体的姿态,本文提出了一种新型数字角速率传感器。该传感器由微传感元件(陀螺仪和加速度计)、信号处理电路和微处理器(DSP2812)组成。该传感器具有同时检测旋转载体的三个角速率的特点。介绍了传感器的关键技术,包括传感结构、传感原理和信号处理电路设计。测试结果表明,该传感器可同时感知横滚、俯仰和偏航角速率,且旋转载体的横摆(或俯仰)角速率和横滚速率测量误差小于0.5%。
With the aim of detecting the attitude of a rotating carrier, the paper presents a novel, digital angular rate sensor. The sensor consists of micro-sensing elements (gyroscope and accelerometer), signal processing circuit and micro-processor (DSP2812). The sensor has the feature of detecting three angular rates of a rotating carrier at the same time. The key techniques of the sensor, including sensing construction, sensing principles, and signal processing circuit design are presented. The test results show that the sensor can sense rolling, pitch and yaw angular rate at the same time and the measurement error of yaw (or pitch) angular rate and rolling rate of the rotating carrier is less than 0.5%.
