This paper proposes a design methodology for linear actuators, considering thermal and electromagnetic coupling with geometrical and temperature constraints, that maximizes force density and minimizes force ripple. The method allows defining an actuator for given specifications in a step-by-step way so that requirements are met and the temperature within the device is maintained under or equal ...

This paper is concerned with the solution bounds for discrete-time networked control systems via delay-dependent Lyapunov–Krasovskii methods. Solution bounds are widely used for systems with input saturation caused by actuator saturation or by the quantizers with saturation. The time-delay approach has been developed recently for the stabilization of continuous-time networked control systems un...

Vibrothermography often employs a high-power actuator to generate heat on a specimen to reveal damage, however, the high-power actuator brings inconvenience to the application and possibly introduces additional damage to the inspected objects. This study uses a low-power piezoceramic transducer as the actuator of vibrothermography and explores its ability to detect multiple surface cracks in a ...

This paper deals with a catalytic continuous stirred tank reactor (CCSTR) example, mo deled as a two-input constrained nonlinear system. Based on the Lyapunov-based linearization strategy, the saturation-type parameterized control design can reduce the effect of actuator subject to amplitude and rate constraints, and the integrated two-input control framework can ensure the asymptotic output re...

The objective of current paper is 3D simulation of turbulent, developing flow and unsteady within a circular duct in presence of the body force vector persuaded by Dielectric barrier discharge (DBD) plasma actuator inside the surface of geometry for the first time. This article aims at investigating of applying plasma actuator to control separation with special arrangement of electrodes. For th...

An understanding of the human motor system, though interesting as a facet of intelligence, would also have application for computer controlled manipulat ion. To enhance this understanding, handwriting is appropriate for study because of its commonality, its susceptibil i ty to measurement, and the possibility of its simulation with a manipulator. A theory of handwriting has been developed and i...

This work addresses the problem of designing a fault-tolerant control system for fluid dynamic systems modeled by highlydissipative partial differential equations (PDEs) with constrained control actuators. The proposed approach is predicated upon the idea of coordinating feedback controller synthesis and switching between multiple, spatially-distributed control actuator configurations. Using ap...

The design of robots that are light, soft, powerful is a grand challenge. Since they can easily adapt to dynamic environments, soft robotic systems have the potential of changing the status-quo of bulky robotics. A crucial component of soft robotics is a soft actuator that is activated by external stimuli to generate desired motions. Unfortunately, there is a lack of powerful soft actuators tha...

This paper interests to the properties of fault-tolerant control system with respect to reliability of components. The aim of this paper is to present the need of reliability analysis in fault-tolerant control design. The focus of our study is on the reconfigurability analysis of systems with actuator faults under reliability constraints. This analysis proves that control reconfigurability is a...
