Stabilization and tracking systems maintain the orientation of optical sensor" payloads" so they are pointed in the scenario dependent directions and held steady in inertial space along the selected orientation. The stabilization-tracking systems are mechanical assemblies that precisely control the angular position of the sensor's line of sight (LOS), so that it is isolated from its base-foundation dynamics and is pointed towards its intended target. These system form part of modern fire

The performance of fire control system mounted on a mobile platform, decreases exponentially with increase in the disturbance on the line of sight (LOS). The conventional controller designed to stabilize the LOS are dependent on mathematical model of the plant. In this modeling process usually the higher order dynamics is ignored and plants are linearized around the operating point. Fuzzy-knowledge-based-controller (FKBC) design presents a good methodology to stabilize the line of sight against disturbances and nonlinearities present in the system, but tuning of input and output membership function parameters is quite a complex process. To overcome this, a choquet fuzzy integral based control algorithm is developed for this servo system with nonlinear property and some uncertainties. In this paper we present the design of FKBC and choquet fuzzy controller and their performance comparison.
