Thermoelectric control of Shape Memory Alloy microactuators: a thermal model

Thermoelectric control of Shape Memory Alloy microactuators:...

smart structures and Materials 1999 conference

Microtechnologies and microsystems engineering use new active materials. These materials are interesting to realize microactuators and microsensors. In this category of materials, Shape Memory Alloys (SMA) are good candidates for microactuation. SMA wires, or thin plates, can be used as active material in microfingers. These microstructures are able to provide very important forces, but have low dynamic response, especially for cooling, in confined environment. The control of the SMA phase transformations, and then the mechanical power generation, is made by the temperature. The Joule effect is an easy and efficiency way to heat the SMA wires, but cooling is not so easy. The dynamic response of the actuator depends on cooling capabilities. The thermal convection and conduction are the traditional ways to cool the SMA, but have limitations for microsystems. We are looking for a reversible way of heating and cooling SMA microactuators, based on the thermoelectric effects. Using Peltier effect, a positive or a negative electrical courant is able to pump or produce heat, in the SMA actuator. A physical model based on thermal exchanges between a Nickel/Titanium (NiTi) SMA, and Bismuth/Telluride (Te3Bi2) thermoelectric material has been developed. For simulation, we use a numerical resolution of our model,with finite elements, which takes into account the Peltier effect, the Joule effect, the convection, the conduction and the phase transformation of the SMA. We have also developed the corresponding experimental system, with two thermoelectric junctions, where the SMA actuator is one of the element of each junction. in this paper, the physical model and its numerical resolution are given, the experimental system used to validate the model is described, and experimental results are shown.

In this paper we consider the problem of deployment of tensegrity structures. Our idea is to make use of a certain set of equilibria to which the undeployed and deployed configurations belong. In the state space this set is represented by a connected equilibrium manifold and can be completely characterized analytically. The deployment is conducted such that the deployment trajectory is close to the equilibrium manifold and the deployment time is minimized.

This paper presents a novel integrated formulation and robust computational tool that can be efficiently employed for the design and analysis of actively controlled smart composite structural systems. The modeling simulation capabilities account for the coupling between thermal, mechanical and electric fields within the framework of an integrated structure/control strategy. The paper also reports the formulation and implementation of an optimization capability for the design and tailoring of smart structural systems. Finally, probabilistic and fuzzy models for rationally and systematically accounting for the uncertainties in structural, control, material, and load parameters are presented. The capabilities are packaged in a comprehensive and user-friendly software system (smartCOM) that can be readily applied for cost-effective design or response characterization of actively controlled smart structures.

smart Structural systems have gained lot of importance now-a-days and have found to have applications in several areas especially in the areas of aerospace, automotive and space applications. One of the essential aspects involved in the integration of smart structures is that of the control system design. Actuator limitation poses as a major obstacle in the real-time implementation of controllers for smart structural systems. This paper gives an account of the application of a controller design procedure to handle control input limitation problem in the design of controllers for smart structures. This procedure, called the limit protection design approach, uses a two-step design procedure to design a control system to achieve graceful degradation of performance in the presence of control input limitation. The solution of the limit protection compensator involves solving a set of bilinear matrix inequalities (BLMIs). An iterative procedure is given for the solution of the BLMIs. Finally, we give the simulation results got from applying the above said procedure on an experimental smart structure.

Tensegrity structures represent a special class of tendon space structures, whose members may simultaneously perform the functions of strength, sensing, actuating and feedback control. The paper exploits this advantage, proposing a smart tensegrity sensor for simultaneous measurement of six quantities: three orthogonal forces and three orthogonal moments. The paper shows how the static and dynamic characteristics of the device can be calibrated through pretension and damping adjustment. The external forces and torques of interest are estimated using the measurements provided by selected tendons. A state estimator, based on the linearized model, finalizes the design.

This paper presents a an integrated finite element based computational methodology for analyzing smart composite structures with piezoelectric sensors and actuators. The method accounts for the coupling of the mechanical, electrical and thermal fields, which these structural systems will be subjected to in practical applications. Three dimensional thermopiezoelectric composite finite elements are used to model the host structure and the piezoelectric sensors and actuators. The finite element equations are integrated with control algorithms based on the linear quadratic regulator (LQR), independent modal space control (IMSC) and the modified independent modal space control (MIMSC), to provide active vibration control capabilities. The capabilities have been incorporated into a computer program called smartCOM. Numerical examples illustrating the computation and/or control of deformations due to thermal excitations are presented and comparisons are made to other methods where possible. The present method provides accurate modelling of the smart structures and is seen as a convenient methodology, in that it permits modelling of the complex behaviour of the smart structure in one integrated package.

A major aim of smart structures is to reduce the amount of materials used to build them while achieving the same amount of dynamic control. This reduction can however lead to a loss of stiffness and a consequent instability of the structure in the presence of stresses. We have turned this problem around by examining how the use of dynamical instabilities can lead to improved control of given patterns in smart structures. In particular, we studied the possibility of dynamically switching between two configurations of a mechanical system, one in which the desired patterns are stable and one in which they are unstable. By comparing the performance of a distributed control in terms of time to switch and power consumption we established that unstable patterns often switch faster among themselves than stable ones without consuming more power.

control of vibration of a base excited cantilever beam is studied in this paper. The algorithm of the control system is based on the concept of active attenuation;the traveling wave of the structural response caused by external excitation can be annihilated by a control wave of opposite signature. Collocated sensor and actuator are used to sensing the traveling wave and generating the control wave. Experimental and numerical results showed that the vibration of a cantilevered beam is substantially suppressed.

Homogenization techniques for determining effective properties of composite materials may provide advantages for control of stiffness and strain in systems using hysteretic smart actuators embedded in a soft matrix. In this paper, a homogenized model of a one-dimensional composite structure comprised of shape memory alloys (SMA) and a rubber-like matrix is presented. With proportional (P) and proportional/integral (PI) feedback, using current as the input state and global strain as an error state, implementation scenarios include the use of tractions on the boundaries and a nonlinear constitutive law for the matrix. The result is a simple model which captures the nonlinear behavior of the smart composite material system and is amenable to experiments with various control paradigms. The success of this approach in the context of the one-dimensional model suggests that the homogenization method may prove useful in investigating control of more general smart structures. Applications of such materials could include active rehabilitation aids, e.g. wrist braces, as well as swimming/undulating robots, or adaptive molds for manufacturing processes.
