Single-channel missile controlling is a method of using a rudder to control the spinning missile to change both pitch and yaw. In essence, the single-channel missile (SCM) control system still follows the dynamic equations of the general aircraft control system, except that the rudder angle signal will simultaneously create control force in both pitch and yaw. Therefore, the method of commanding the single-channel missile rudder has its own characteristics and plays a role in distinguishing the single-channel missile control system from other aircraft control systems. The commanding methods that have been proposed are ON-OFF commanding and continuous sinusoidal signal commanding. This paper presents a method for establishing a single-channel missile control command using the amplitude pulse method. By approaching the desired total control force according to the error, the rudder angle changes according to the amplitude pulse law. This commanding method can be applied to similar lines of rudders, making it more convenient in modern control.
