The controller robustness is guaranteed despite the uncertainties in dynamic model caused by payload variation, imprecise modeling, etc.
The inner force occurs because the motion of the manipulator cannot follow the position of the handle exactly due to the positional error and the imprecise modeling of the door, while a firm grasp compels the manipulator to follow.
The second issue is how to release the inner force in the manipulator that occurs during turning the handle and pushing the door because of the positional error and the imprecise modeling of the environment.
Simulation shows that the technique proposed yields controllers with performance minimally affected by an imprecise modeling of an induction motor, as well as a reduced cost controller implementation throughout the entire induction motor operating sequence.
In turn, this means that even though we may not have polls in every state on every day, we've got a plausible (if imprecise) model of movement in one state that might be related to movements in another state, and a model that links up state and national level changes in the vote.
Another question Miller-Jones raised is whether rodents are an imprecise model for effect of fructose, given that de novo lipogenesis constitutes 60 70% of fat synthesis in rodents far more than the 10 20% in humans.
When we considered the model with combined maternal and paternal PBB exposure, the odds ratio for offspring where both parents had PBB exposure ≥ the median concentrations (≥ 3 μg/L for mothers and ≥ 6 μg/L for fathers) compared to where both parents had PBB exposure < the median concentrations was increased, but imprecise (Model 3, n = 300 offspring, n = 171 pairs of mothers and fathers).
An imprecise model affects the capabilities of the analyses carried out with it (such as the statistical power to detect the pathways that are significantly impacted in a given condition), since it will not make use of the complete biological information available.
