Multi-input and Multi-variable systems

480
Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.

Collisions in Multiple Dimensions: Problem Solving

5.6K
In multiple dimensions, the conservation of momentum applies in each direction independently. Hence, to solve collisions in multiple dimensions, we should write down the momentum conservation in each direction separately. To help understand collisions in multiple dimensions, consider an example.
A small car of mass 1,200 kg traveling east at 60 km/h collides at an intersection with a truck of mass 3,000 kg traveling due north at 40 km/h. The two vehicles are locked together. What is the...

Observational Learning01:12

Observational Learning

1.2K
Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...

Rolling Resistance: Problem Solving01:17

Rolling Resistance: Problem Solving

923
Rolling resistance, also known as rolling friction, is the force that resists the motion of a rolling object, such as a wheel, tire, or ball, when it moves over a surface. It is caused by the deformation of the object and the surface in contact with each other, as well as other factors like internal friction, hysteresis, and energy losses within the materials. Rolling resistance opposes the object's motion, requiring additional energy to overcome it and maintain movement. In practical...

Associative Learning01:27

Associative Learning

1.9K
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Hierarchy of Motor Control01:18

Hierarchy of Motor Control

6.8K
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.

    Area of Science:

    • Artificial Intelligence
    • Robotics
    • Machine Learning

    Background:

    • Reinforcement learning (RL) is widely used for autonomous driving (AD) decision-making and control.
    • Current RL methods struggle with multi-objective compatibility in complex driving scenarios, affecting policy updating and execution.
    • Limitations include single value evaluation networks and single-type action spaces, hindering flexibility and causing behavioral fluctuations.

    Purpose of the Study:

    • To propose a novel multiobjective ensemble-critic (MoEC) reinforcement learning (RL) method for compatible autonomous driving (AD).
    • To address challenges in policy updating and execution for multi-attribute driving problems.
    • To enhance driving flexibility, reduce behavior fluctuations, and improve decision-making in complex scenarios.

    Main Methods:

    • Developed a multiobjective ensemble-critic (MoEC) RL architecture for autonomous driving (AD).
    • Integrated a hybrid parameterized action space generating abstract guidance and concrete control commands.
    • Implemented an uncertainty-based exploration mechanism to accelerate learning of multi-objective compatible policies.

    Main Results:

    • The MoEC method demonstrated efficient learning of multi-objective compatible autonomous driving (AD) policies.
    • Evaluated performance in both simulator-based and HighD dataset-based multilane highway scenarios.
    • Achieved improvements in efficiency, action consistency, and safety compared to existing methods.

    Conclusions:

    • The proposed MoEC RL method effectively addresses multi-objective compatibility challenges in autonomous driving (AD).
    • The hybrid action space and ensemble-critic architecture enhance policy updating and execution.
    • The approach leads to more efficient, consistent, and safer autonomous driving (AD).
