2015MEMS、The application of sensor hardware as the main component can be described as shining brightly.
MEMSacceleration transducer Upon investigation, this is due to Due to the fact that acceleration sensors can utilize the principle of force decomposition, the inclination angle can be determined by the components of gravity acceleration in different axes. At the same time, it has no integration error, so the accelerometer can effectively correct the error of the gyroscope under relatively stationary conditions. But in the state of motion,acceleration transducer At present, the most common algorithm for unmanned aerial vehicles in applications is to use complementary filtering, that isCombine the outputs of the accelerometer and gyroscope to calculate the angle change.
MEMS For example, the ideal output of a gyroscope is to only respond to changes in angular velocity, but in reality, it is limited by design and process,gyroscopedeg/sec/g ACC326 and ACC326H are small and low-cost serial output three-axis digital accelerometers, with output modes of RS232, RS485, CAN, or TTL level interface standards available. The product adopts the latest microelectromechanical production technology for tilt angle units, which have small size, low power consumption, high consistency and stability. As a digital sensor, linearity is easier to correct, compensating for the accuracy decline caused by insufficient correction of analog products. The working temperature reaches industrial grade -40 to+85 ℃, making it a cost-effective unmanned aerial vehicle acceleration sensor.
