Description
Block Precision Pilot Model It represents the pilot model described in Mathematical Models of Human Pilot Behavior [1]. This pilot model provides greater accuracy than the blocks. Tustin Pilot Model and Crossover Pilot Model. This model has a non-linear behavior. When calculating, the model also takes into account the neuromuscular dynamics of the pilot.:
where
-
— pilot’s gear ratio gain;
-
— the constant delay of the pilot, with;
-
— the time constant of the numerator of the pilot’s transfer function, with;
-
— the time constant of the denominator of the pilot transfer function, with;
-
— the time constant of the neuromuscular system;
-
— frequency of the neuromuscular system;
-
— the damping coefficient of the neuromuscular system.
