چکیده

Heat Equation Driven Area Coverage (HEDAC) is a state-of-the-art multi-agent ergodic motion control guided by gradient of potential field. A finite element method hereby implemented to obtain solution the Helmholtz partial differential equation, which models field for surveying control. This allows us survey arbitrarily shaped domains and include obstacles in an elegant robust manner intrinsic HEDAC's fundamental idea. For simple kinematic motion, boundary avoidance constraints are successfully handled directing agent with potential. However, including additional constraints, such as minimal clearance distance from stationary moving path curvature radius, requires further alternations algorithm. We introduce relatively yet approach handling these formulating straightforward optimization problem based on collision-free escape route maneuvers. provides guaranteed collision mechanism while being computationally inexpensive result partitioning. The proposed evaluated three realistic scenarios simulations, showing effectiveness robustness Furthermore, maneuvering difficulties due improperly defined highlighted we provide guidelines how overpass them. results promising indicate real-world applicability constrained autonomous potentially other HEDAC utilizations.

Formation Constrained Multi-Agent Control

We propose a model independent coordination strategy for multi-agent formation control. The main theorem states that under a bounded tracking error assumption our method stabilizes the formation error. We illustrate the usefulness of the method by applying it to rigid body constrained motions.

A Multi-Physics Simulation Model Based on Finite Element Method for the Multi-Layer Switched Reluctance Motor

Using ANSYS finite element (FE) package, a multi-physics simulation model based on finite element method (FEM) is introduced for the multi-layer switched reluctance motor (SRM) in the present paper. The simulation model is created totally in ANSYS parametric design language (APDL) as a parametric model usable for various conventional types of this motor and it is included electromagnetic, therm...
