“…Guidance represents a fundamental methodology which transcends specific vehicle applications (Draper, 1971), and is concerned with the transient motion behavior related to the achievement of motion control objectives (Shneydor, 1998). For this reason, guidance laws are typically stated at a kinematic level, only considering the fundamental geometric aspects of the scenarios of interest.…”

This paper considers the subject of straight-line target tracking for unmanned surface vehicles (USVs). Target-tracking represents motion control scenarios where no information about the target behavior is known in advance, i.e., the path that the target traverses is not defined apriori. Specifically, this work presents the design of a motion control system which enables an underactuated USV to track a target that moves in a straight line at high speed. The motion control system employs a guidance principle originally developed for interceptor missiles, as well as a novel velocity controller inspired by maneuverability and agility concepts found in fighter aircraft literature. The performance of the suggested design is illustrated through full-scale USV experiments in the Trondheimsfjord.

“…According to MacKenzie, guidance is defined as the procedure for guiding the path of an object toward a given point [1,4]. Moreover, Charles Stark Draper stated that Guidance depends on main basics and includes vehicles steering in different environments beyond the atmosphere with the gravitational field and in space [1,5]. The most wealthy and ripe for guidance is established with the steering missile.…”

The purpose of this paper is to control the trajectory of the nonlinear missile model in the pitch channel by using Fractional PID controller (FPID) and Gain Schedule Fractional PID controller (GSFPID). FPID and GSFPID with nonlinear missile model are designed where their parameters are tuned by Simulink design optimization in the Matlab toolbox. This optimization method gives the optimal parameters that achieve the best tracking with step unit reference signal. The GSF-PID controller compensates the restrictions that represent physical limits of actuators in the pitch channel. The GSFPID with nonlinear missile model is designed in two phases. The first phase is the boost phase where the thrust force is maximized and the second phase is sustain phase where the thrust force is minimized. The equations of motion for nonlinear missile model with FPID and GSFPID are modelled mathematically in the Matlab-Simulink environment. The results of FPID and GSFPID controllers with the nonlinear missile model are presented and compared. The wind effect and the dynamic uncertainties effects are researched and the results are compared. The closed-loop nonlinear system is linearized by the Simulink linear analysis tool at critical operating point t = 5.8 sec and the stability is studied.

“…According to MacKenzie, guidance is defined as the procedure for guiding the rout of an object toward a given point, that in general is moving, [1,3]. Moreover, the father of inertial navigation, Charles Stark Draper, states that ''Guidance depends on main principles and involves devices that are same for vehicles moving on land, on water, under water, in air, beyond the atmosphere within the gravitational domain of earth and in space outside this domain, [1,4]. The most rich and ripe literature on guidance is found within the guided missile society.…”

The goal of this paper is to control the trajectory of the flight path of six degree of freedom flying body model using Fractional PID controller (FPID) and Gain Schedule Fractional PID controller. FPID and gain schedule FPID controllers gains with non linear flying body simulation are tuned by Simulink design optimization. Gain Schedule FPID controller is able to compensate for constraints that represent physical limits of actuators in pitch angle. The gain schedule FPID for the six degree of freedom flying body is designed in two phases. The first phase is boost phase where the thrust force is maximized. The second phase is sustain phase where the thrust force is minimized. The results of gain schedule FPID controller are compared with the results of FPID controller.
