Due to the Force Generator Force-Time characteristic, it takes time to activate the Force Generator. fgen_get_activation is a function that represents the activation level at current_time

Usage

fgen_get_activation(
  current_time,
  initial_activation = 0,
  time_to_max_activation = 0.3
)

Arguments

current_time	Numeric vector
initial_activation	Numeric vector between 0 and 1. Default is 0
time_to_max_activation	Numeric vector. Time it takes to reach maximal activation from 0. Default is 0.3s.

Value

Numeric vector. Activation level at current_time

Examples

x <- seq(0, 1, length.out = 1000)

y1 <- fgen_get_activation(
  current_time = x,
  initial_activation = 0,
  time_to_max_activation = 0.5
)

plot(x, y1, "l")

y2 <- fgen_get_activation(
  current_time = x,
  initial_activation = 0.2,
  time_to_max_activation = 0.5
)

lines(x, y2, col = "red")

y3 <- fgen_get_activation(
  current_time = x,
  initial_activation = 0,
  time_to_max_activation = 0.4
)

lines(x, y3, col = "blue")
