It is necessary to make camera images from helicopters stable in response to helicopter swaying. As a general method of control, reliable PID control is used widely. We have developed a control algorithm which switches the parameter of PID control according to the situation of operation to the camera mount. This algorithm was applied to the camera mount in which it is carried by the helicopter. The validity of this was also checked. The main conclusions are shown below.
(1) This technique is control algorithm intuitive and intelligible, and two or more control parameters in which compatibility is difficult can be satisfied simultaneously.
(2) This technique asks for the optimal control parameter of each state. Therefore, identification of a system is possible in a short time.
