Summary
This summary is machine-generated.This study introduces a grouped prescribed-time cooperative guidance law (GPCGL) for multiple vehicles to attack targets without collision. The GPCGL ensures cooperative attacks and collision avoidance within a set time frame.
Area Of Science
- Robotics and Control Systems
- Autonomous Systems
- Guidance, Navigation, and Control (GNC)
Background
- Cooperative guidance for multi-vehicle systems is crucial for complex missions.
- Collision avoidance remains a significant challenge in coordinated attacks.
- Prescribed-time control offers precise temporal guarantees for system convergence.
Purpose Of The Study
- To propose a novel Grouped Prescribed-Time Cooperative Guidance Law (GPCGL) for multi-vehicle target attack without collision.
- To enable coordinated attacks with temporal precision and ensure safety among vehicles.
- To address cooperative guidance and collision avoidance within subgroups of vehicles.
Main Methods
- A distributed guidance law for leaders to achieve separated time attacks.
- A two-part guidance law for followers: tangential and normal directions in the follower-to-leader line-of-sight (LOS) frame.
- A proportional consensus guidance law with an auxiliary control term for intra-subgroup cooperation and distance-based collision avoidance.
- A dynamic LOS angle constrained guidance law for direction-based collision avoidance.
Main Results
- The proposed GPCGL guarantees intra-subgroup cooperation and simultaneous distance-based collision avoidance.
- Direction-based collision avoidance is achieved through a dynamic LOS angle constrained guidance law.
- The GPCGL is proven to be prescribed-time convergent, ensuring state convergence within a specified time.
- Simulations validated the effectiveness of the proposed guidance law.
Conclusions
- The GPCGL effectively enables multiple vehicles to cooperatively attack multiple targets without collision within a prescribed time.
- The guidance law ensures both cooperative behavior and robust collision avoidance through distinct control strategies.
- The prescribed-time convergence property offers predictable mission completion times.

The discussion of bullying highlights the problem of witnesses not intervening to help a victim. This is a common occurrence, as the following well-publicized event demonstrates. In 1964, in Queens, New York, a 19-year-old woman named Kitty Genovese was attacked by a person with a knife near the back entrance to her apartment building and again in the hallway inside her apartment building. When the attack occurred, she screamed for help numerous times and eventually died from her stab wounds.
Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
In power systems, the entire setup is divided into protective zones to isolate faults and protect the rest of the network. These zones include generators, transformers, buses, transmission lines, distribution lines, and motors. Each zone can be visualized as a separate room in a house, with each room protected by its own circuit breaker.
Protective zones are defined by closed dashed lines, containing one or more components. A key characteristic of these zones is the strategic placement of...
GPS surveying methods vary in application, accuracy, and data collection techniques, catering to diverse surveying and mapping needs. Static GPS, kinematic GPS, and real-time kinematic (RTK) surveying are widely used. Each technique offers distinct advantages.Static GPS involves placing one receiver at a known reference point and another at the target point. It collects exact positional data by observing multiple satellite ranges over an extended period, achieving centimeter-level accuracy for...
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.
Three-Spined Sticklebacks
A classic example of a FAP was described in three-spined stickleback fish by Nikolaas Tinbergen in the 1930s. During the breeding season, the male fish develop a red...
B.F. Skinner, a prominent figure in behavioral psychology, introduced operant conditioning by emphasizing the role of consequences in shaping behavior. This theory builds upon the law of effect proposed by Edward Thorndike, which posits that behaviors followed by satisfying outcomes are likely to be repeated. In contrast, those followed by unsatisfying outcomes are less likely to recur.
Edward Thorndike's foundational work involved studying learning in animals, particularly using puzzle...
