In this article, we describe a collaborative approach to develop, integrate, and assess a teaching module on smart actuators specifically designed to embed topics in nano/bio technology into the undergraduate mechanical engineering (ME) curriculum. The collaboration involves three universities, each focusing on one specific aspect of the module. The module consists of lectures and laboratory activities that cover modeling and control of smart actuators for courses such as system dynamics, controls, and mechatronics. The integration of smart actuators — such as piezoelectric, shape memory alloy (SMA), and magnetostrictive based devices — into the ME curriculum is important because these devices are the workhorse in a multitude of nano and bio technologies. Thus, these devices play a critical role in the emerging areas, analogous to the benefits of the electric motor at the macroscale. But contrast to the well established coverage of the electric motor in the ME curriculum, modeling and control of smart actuators has yet to be systematically presented in core ME courses. The contribution of this article is presenting the systematic development, integration, and assessment of a teaching module on smart actuators. We first describe the design of lecture components using the piezo actuator as an example. The lecture materials cover core concepts within the framework of dynamics and controls, such as electromechanical coupling, dynamic response, nonlinear input-output behavior, and PID feedback control technique for high-precision positioning. Afterwards, we describe the development of a hands-on laboratory experiment designed to expose students to the basics of experimental modeling of the piezo actuator. The platform is also suited for basic control applications, and an example is presented to illustrate the application of piezo actuator control for high-precision positioning. The paper concludes with a discussion on how the module will be implemented and assessed at the three participating universities.

In this study, piezoelectric actuator, Flexure guide, Power transmission element and control method and considered for Nano-positioning system apparatus. The main objectives of this thesis were to develop the 3-axis Ultra-precision stages which enable the 3-axis control by the manipulation of the piezoelectric actuator and to enhance the precision of the Ultra-Precision CNC lathe which is responsible for the ductile mode machining of the hardened-brittle material where the machining is based on the single crystal diamond. Ultra-precision CNC lathe is used for machining and motion error of the machine are compensated by using 3-axis Ultra-precision stage. Through the simulation and experiments on ultra-precision positioning, stability and priority on Nano-positioning system with 3-axis ultra-precision stage and control algorithm are secured by using NI Labview. And after applying the system, is to analyze the surface morphology of the mold steel (SKD61)

In order to reduce the costs of implementing the radial position control system of a three-phase bearingless machine with split winding, this article proposes a driving method that uses only two phases of the system instead of the three-phase traditional one. It reduces from six to four the number of inverter legs, drivers, sensors, and current controllers necessary to drive and control the system. To justify the proposal, this new power and control configuration was applied to a 250 W machine controlled by a digital signal processor (DSP). The results obtained demonstrated that it is possible to carry out the radial position control through two phases, without loss of performance in relation to the conventional three-phase drive and control system.
