Collision avoidance control law of a helicopter using information amount feedback

Utilization of helicopter in urban area is increasing because of its special flight performance. Collision avoidance guidance will play an important role in the future guidance of helicopters. All information of other aircraft is not always available for collision avoidance due to climate conditions or communication problems. Helicopter has to avoid other helicopter under such uncertain information conditions. This paper proposes that a controller uses the information amount as same as physical values. The helicopter changes the flight course to increase the information amount using dynamics of information. Collision avoidance law is adopted when approaching helicopters is recognized. Avoidance is to increase the minimum distance between two helicopters. Numerical simulations show that the helicopter using the information amount avoids the approaching one with safe distance.
