“…Because the guidance signals produced by the LHG law are in terms of the angle between the velocity vector of point P and lateral axis, the control variable of the robotic arm control system is chosen to be the joint speeds, i.e., _ θ 1 and _ θ 2 [6]. Since the main objective is the speed control of point P, the control system based on the joint speeds corresponds to an indirect control scheme.…”

“…The type of the command yielded by the guidance system depends on the selected guidance law. Namely, as the output of the proportional navigation guidance law which constitutes the most widely used guidance law in guided munitions is the lateral component of the linear acceleration vector of the munition or change of the lateral angular component of the linear velocity vector in time as per the application, the command of the body pursuit guidance law becomes the components of the angle between the body longitudinal axis of the munition and the lateral axis of the Earth-fixed frame [5,6].…”

Motion planning is a significant stage in the control of autonomous systems. As an alternative method, guidance approach is proposed for the motion planning of those systems. In guided munitions, guidance laws determine the success of the guidance systems designed to steer systems such as missiles and guided bombs towards predefined targets. The guidance laws designated according to determinative agents such as the firing position of the munition, target type, and operational requirements try to provide the munition with arriving at the target point even under the disturbing effects. In this study, the applicability of the guidance laws to autonomous systems is investigated in a manner similar to the approach for the guided munitions. For this purpose, the motion planning of the selected robotic arm, tracked land vehicle, and quadrotor is tried to be performed in order to move them to predefined target points. Having designed the control systems compatible to the selected guidance laws for the considered systems, the corresponding guidance scheme is constructed. Eventually, after conducting the relevant computer simulations, it is observed that the desired target chase can be made in a successive manner for all cases.

Short-range air-to-surface missiles have become globally popular in the last two decades. As a performance driver, the type of guidance law gains importance. In this study, proportional navigation, velocity pursuit, and augmented proportional navigation guidance laws, whose resulting guidance commands take the form of lateral acceleration, are applied to a short-range air-to-surface missile against both stationary and maneuvering ground targets. Body pursuit and linear homing guidance laws, which yield angular commands, are additionally applied. Having completed the relevant computer simulations, we conclude that none of the acceleration-and angle-based guidance laws are absolutely superior to the others.

In this study, the generic dynamic models of air-to-surface missiles are given in addition to the related guidance and control schemes. In this extent, two-part missile configurations are considered as well as the traditional single-part missile geometries. The dynamic modelling part consists of the general equations of motion for both of the mentioned types of missile configurations, aerodynamic modelling and corresponding transfer functions, which are used in the design of missile autopilots. Further, the notable guidance laws applicable to such missiles are given along with the relevant autopilot, or missile control system, models. Regarding the mission profile of these munitions, the target is modelled as a surface vehicle moving on the ground. After conducting some computer simulations based on the proposed models, the study is concluded by a general evaluation section.
