Design of an Output Feedback Trajectory Controller for an Automated Guided Vehicle
نویسندگان
چکیده
This paper presents the design of an output feedback trajectory controller for a Automated Guided Vehicle (AGV) differential drive. Its control architecture assumes that the two drive wheels are not coupled and the vehicle dynamics is not taken into account. It employs two independent velocity controllers that ensure the wheels’ velocities referenced by the trajectory controller. The reference trajectory is painted on the ground and is composed only by line segments and soft arcs. Simulation and experimental results show the satisfactory tracking performance of the proposed controller. Key Words— Robot control; mobile robots; nonlinear systems; trajectory tracking; control schemes.

The AGV (automated guided vehicle) was introduced in UK in 1953 for transporting. But nowadays, due to their high efficiency, flexibility, reliability, safety and system scalability, they are used in various application in industries. In brief, the AGV robot is a system which typically made up of vehicle chassis, embedded controller, motors, drivers, navigation and collision avoidance sensors, ...
متن کاملDesign of an Intelligent Controller for Station Keeping, Attitude Control, and Path Tracking of a Quadrotor Using Recursive Neural Networks
During recent years there has been growing interest in unmanned aerial vehicles (UAVs). Moreover, the necessity to control and navigate these vehicles has attracted much attention from researchers in this field. This is mostly due to the fact that the interactions between turbulent airflows apply complex aerodynamic forces to the system. Since the dynamics of a quadrotor are non-linear and the ...
