Error Reduction in a Two-Gimbal, Airborne, Angle Track System.
Abstract
Angle measurement in a two-gimbal, airborne, tracking system is complicated by the motion of the aircraft. The two-gimbal system is characterized by the azimuth and elevation channel control systems. Rolling motions introduce error-causing disturbance inputs into each channel. One method of reducing the error investigated in this report is a linear transformation method which treats both channels simultaneously by considering a cross-coupled multivariable system. Another method, the invariance method, utilizes a feed forward branch whose input is the unwanted disturbance to reduce the error due to aircraft roll rate for each channel separately.
