... ) In this paper, the control action φ fb ( θ ) is provided by a PI controller. In particular, control parameters are scheduled on the basis of the in-cylinder air mass so that the closed-loop poles are kept fixed to preassigned values for each steady-state engine operating condition. Model...

... are considered by Hertz contact model and are evaluated by Gauss quadrature. The proportional integral (PI) control law for web guiding is also embedded in the multibody model. A series of simulations on a typical web-guide system is carried out using the multibody dynamics approach for web guiding system...

... on the manipulator can be independently programmed. The results presented herein show stable and satisfactory tracking behavior during free motion, interaction, and transition tasks for a robot control system inspired by the EP hypothesis and implemented with a linear proportional-integral (PI) control strategy...

... nonlinearity of the PA is modeled by using Preisach model first. Then a database of switching input/output values and a neural networks architecture treated as the inverse function of Preisach model are utilized in the feedforward controller. In the feedback controller design, a PI controller is used...
