Optical microstructure arrays on metallic surfaces are drawing ever-increasing attention due to the increasing requirements in optical systems. Although vibration generators developed for generating microarrays with ultra-precision diamond cutting process, systematic research works its mechanical design, working performance simulation, and numerical simulation of has received less attention. In...

Robust DC-DC converters which can cover extensive load changes and also input voltage changes are needed. In this paper, we propose a new method for designing good approximate 2-degree-of freedom (2DOF) digital controller which makes the control bandwidth wider, and at the same time makes a variation of the output voltage very small at sudden changes of resistive load. The proposed approximate ...

In this paper we aim at polynomial synthesis of a two-degree-of-freedom (2DoF) controller with integral action for a coupled tank system using the Polynomial Toolbox. The main advantage of the proposed 2DoF controller is in computational savings compared to classical feedback design. It will be shown that the procedure leads to solving of two spectral factorizations where the closed loop poles ...

A computationally efficient quasi-two-degree-of-freedom (Q2DOF) stochastic model and a stability analysis of barges in random seas are presented in this paper. Based on the deterministic 2DOF coupled Roll-Heave model with highdegree polynomial approximation of restoring forces and moments developed in Part I, an attempt is made to further reduce the DOF of the model for efficient stochastic sta...

To reproduce the sensation of rubbing on a surface, we need to laterally stretch the skin of the fingertip with two degrees of freedom (2DOF). Unfortunately, it is difficult to develop a compact 2DOF device for the fingertip because at least two actuators are required. However, if we can perceive the rubbing sensation regardless of the skin stretching direction, a device with 1DOF is sufficient...

Robust DC-DC converter which can cover extensive load changes and also input voltage changes with one controller is needed. In this paper, we propose a method for determining the parameters of 2DOF digital controller which makes the control bandwidth wider, and at the same time makes a variation of the output voltage very small at sudden changes of resistive load and the input voltage. The 2DOF...

In this paper, we propose a method of applying a two-degreeof-freedom (2DOF) control with adaptive filter since such control of an electrodynamic shaker that is not permitted to employ the iteration control method. At first, a mathematical model and an uncertainty weighting are introduced, and a feedback controller is designed using μ-synthesis. 2DOF controller is constituted. Next, an adaptive...

This contribution is focused on continuous-time control of interval systems by means of two-degree-of-freedom (2DOF) configuration. The controller design utilizes algebraic techniques in the ring of proper and (Hurwitz-)stable rational functions (RPS). Robust stability of resulting 2DOF loops is analyzed graphically, namely with the assistance of the value set concept and the zero exclusion con...

This study proposes an adaptive control method of a weigh feeder. A weigh feeder dispenses material into a process at a precise rate, and it has been employed in industries, e.g., process control, cement manufacturing plants, food industry equipment, and so on. To introduce advanced control into industries, self-tuning controllers are designed for controlling a weigh feeder. Three difference co...
