There are so many application areas such as mechatronic field etc. In mechatronic trajectory controller is of great use. To control the trajectory closeness of trajectory points is very important and all projects are stick to the basics of coordinate system. The target of all the projects is entirely focused on reducing the error between the estimated values to the actual one. So far this concept is working but if the noises are introduced the refinement is required. Surveyed paper’s methodologies are worked out with fuzzy logic and neural network. There are lot of things to be consider when comes to the trajectory tracking comes into the picture such as torque, angular rotation etc. This survey paper brings all the aspects and problems of trajectory tracking and solution to that problem.
