Problems solved by technology

The human sensor system of the passive side stick can only provide an electrical signal output proportional to the stick displacement, and the stick force and stick displacement characteristics are provided by mechanical devices such as internal spring damping systems, thus cutting off the mechanical connection between the driver and the rudder surface , so that the pilot cannot intuitively feel the flight status information of the aircraft
At present, Airbus aircraft are all passive side sticks, and passive side sticks will have some defects: the two sides are not...

technical field [0001] The invention relates to the technical field of pilot control platforms, in particular to a civil aircraft man-in-the-loop system with an active side stick and its corresponding active side stick servo tracking control system and servo control method. Background technique [0002] Active Side Stick Control System (ASSCS) is a new pilot control platform. As a new type of driving system to make up for the shortcomings of the passive sidestick, the active sidestick control system can provide the pilot with tactile and visual feedback about the flight status of the aircraft, so that the pilot can better perceive the flight status of the aircraft. [0003] Civil aircraft sidestick control is usually divided into passive sidestick and active sidestick. The human sensor system of the passive side stick can only provide an electrical signal output proportional to the stick displacement, and the stick force and stick displacement characteristics are provided b...
