Characteristics of inertial sensors and their experimental analysis;

For the research of a pendulous inertial sensor,it is quite important to measure the mechanical bias.

Present state and perspectives of micromachined inertial sensors;

Through the data fusion of output information of inertial sensors(including accelerometer and gyroscope) and the T-S fuzzy model,the research of the balance and the trajectory tracking of the two-wheeled self-balance robot was completed.

With the aid of inertial sensor and range sensor,a coarse-to-fine strategy was adopted to locate the moving objects in the video sequence.

In electro-optical tracking system,fractal noises and white noises have main effects on the precision of inertial sensors,and it is difficult to filter fractal noises by traditional methods.

Since a vector speed could influence the gyro and accelerometer\'s signals which could affect the gyrocompass alignment,the strapdown gyrocompass correction method of inertial sensors was developed to filter the gyro and accelerometer\'s signals,and the formula of correction method was also deduced.

An attitude estimation system based on the inertial sensors was proposed.
