A tail chase guidance system for directing a steerable object, such as a pedo, to a contact along a final approach course. The guidance system senses a bearing from the steerable object to the contact and the course of the steerable object. If the contact is moving, the system determines a contact course as a final approach course; if stationary, a value is provided for the final approach course. Various signals are then generated based upon these bearings and courses and classified into sensed linguistic variables based on membership functions from the different sensed variable membership function sets to become fuzzy inputs to a controller that produces fuzzy control output linguistic variables and associated membership functions from a control output membership function set based upon logical manipulation of the fuzzy inputs. These fuzzy control output membership functions are converted into an output having an appropriate form for controlling the trajectory so that the steerable object intercepts the contact along the final approach course.

[ What is claimed is:] [1.] A system residing on a launching site for guiding a steerable object from said launching site to a contact comprising:means for generating bearing and course signals at the launching site representing the bearing from and course of the steerable object to the contact and a final approach course along which the steerable object is to intercept the contact;error signal means responsive to the signals from said generating means for generating a first sensed variable signal based upon the bearing from the steerable object to the contact and the final approach course and a second sensed variable signal based upon the bearing from the steerable object to the contact and the course of the steerable object;fuzzy control means responsive to said first and second sensed variable signals for generating a guidance command at the launching site for remotely controlling the steerable object from the launching site; andmeans for transferring the guidance command from the launching site to the steerable object whereby the steerable object is guided along a trajectory to intercept the contact along the final approach course.
