| Popis: | The paper presents a new method to eliminate acceleration disturbance in level attitude measurement and control of moving carrier. Output signals of micro-machined inclinometer and gyroscope are analyzed in different states of moving carrier by experimental simulation, results show that gyroscope almost keeps the zero output voltage while inclinometer outputs in significant fluctuations. With the analysis results, a new method on acceleration disturbance suppression is developed base on a combination of inclinometers and gyroscopes, which includes establishment and derivation of its mathematical model and implementation, and an algorithm software design. Finally, tests to the acceleration disturbance suppression effect are demonstrated in line motion, line vibration, angular motion and angular motion plus pitch swing. Experimental results show that the method achieves its expected effect. The inertial system constitutes of inclinometers and gyros interacting with acceleration disturbance suppression method can dynamic detect the level attitude of moving carrier. |
