The weights of an optimum PB (Pre-steered broadband) antenna array processor are often obtained by solving a LCMV (linearly constrained minimum variance) problem. The objective function is the mean output power (variance) and the constraints space is a set of linear equations which ensure a constant gain in a fixed direction known as the look direction.(More)
Posture balance and path tracking control of disk rolling without slipping on the horizontal plane was researched. Non-holonomic restriction model of disk rolling without slipping was built, considering most easiness of disk posture control, a posture balance condition was put forward, and based on the posture balance condition, using Lyapunov's stability(More)
