The code provided is a computational model designed to incorporate feedback delays into the dynamics of a system that controls reaching movements in humans. It aims to augment the state-space representation of the system by integrating feedback delays due to neural processing times. This augmentation allows for the modeling of how motor control systems in the brain adjust and compensate for these delays.
State-Space Representation:
Feedback Delay:
delay
represents the neural or systemic feedback delay, crucial in biological systems where sensory feedback takes time to be processed by the brain and translated into motor actions. Such delays could arise from synaptic transmission, neuronal processing, or sensory integration in motor areas such as the motor cortex or cerebellum.Discretization Step:
delta
is a representation of the discretization step, which is important in biological systems to simulate continuous processes like neuronal firing or muscle activation in a discretized manner through computational models.Robust Control in Biological Systems:
Motor Cortex and Cerebellum:
Sensory Feedback:
Compensation for Delays:
Overall, the code models a fundamental aspect of human motor control, focusing on incorporating feedback delays that occur in biological systems. By doing so, it provides insights into the processes underlying robust control strategies employed by the CNS to achieve smooth and accurate motor actions in the presence of inherent system delays.
