On February 21, 2006, the National Academy of engineering recognized the achievements of the Learning Factory with the Bernard M. Gordon Prize for Innovation in engineering and Technology Education. The co-founders were commended “for creating the Learning Factory, where multidisciplinary student teams develop engineering leadership skills by working with industry to solve real-world problems.” This paper describes the origins, motivation, philosophy, and implementation of the Learning Factory. The specific innovations of the Learning Factory partnership were: active learning facilities, called Learning Factories, that provide experiential reinforcement of engineering science, and a realization of its limitations; strong collaborations with industry through advisory boards, engineers in the classroom, and industry-sponsored capstone design projects; practice-based engineering courses integrating analytical and theoretical knowledge with manufacturing, design, business concepts, and professional skills; and dissemination to other academic institutions (domestic and international), government and industry.

This paper presents discrete sliding mode control (DSMC) for nonlinear model of an inverted pendulum system. The reaching law method is used during the DSMC design. The uncertainties are structured in that system by considering the existence of an error during the pendulum angle measurement. The designed controller is compared with Linear Quadratic Regulator (LQR) controller to observe the capability for controlling the highly nonlinear system of the inverted pendulum. The performance and reliability of the proposed algorithm are determined by performing extensive simulation works using MATLAB/Simulink platform. The result shows that DSMC can produce better response as compared to LQR control strategy. © 2011 IEEE.

This paper presents the position tracking performance of an electro-hydraulic hydraulic actuator (EHA) system by using a discrete sliding mode control (DSMC). A point-to-point trajectory is used in the experimental works to evaluate the performance of the DSMC which is design in two-degree-of-freedom (2-DOF) control structure. The design consists of DSMC and a feed forward controller. The control law is derived from the reaching law concept and its parameters are determined methodically based on the identified model. Experimental results reveal that the DMSC with 2-DOF control structure is highly robust and capable to deal with the uncertainties and disturbances occur during the position tracking control for different point of trajectories. It is also shows that the proposed controller can achieve better tracking performance as compared to conventional LQR and PID controller. © 2011 IEEE.

This article describes the problem of the automatic production of a tuning fork with a tip for atomic force microscopy (AFM). It contains hardware and software (image processing) description of a self acting machine developed to solve the problem. The image processing main goal is to measure distances between individual parts during the fabrication process. A camera with high resolution and macro objective is used to acquire images during the assembly process. For getting better results, we perform correction of the used camera distortion and its calibration. Together with proposed image processing methods we use the camera as an accurate distance sensor. So obtained data we then used to control the process. We implemented proposed image processing methods in C++ using Intel OpenCV library. The machine is able to produce the tuning fork with the tip with constant parameters, which is important for future work with the microscope. © 2011 IEEE.

This paper presents finite state control (FSC) of paraplegic walking with wheel walker using functional electrical stimulation (FES) with spring brake orthosis (SBO). The work is a first effort towards restoring natural like swing phase in paraplegic gait through a new hybrid orthosis, referred to as spring brake orthosis (SBO). This mechanism simplifies the control task and results in smooth motion and more-natural like trajectory produced by the flexion reflex for gait in spinal cord injured subjects. The study is carried out with a model of humanoid with wheel walker using the Visual Nastran (Vn4D) dynamic simulation software. Stimulated muscle model of quadriceps is developed for knee extension. Fuzzy logic control (FLC) is developed in Matlab/Simulink to regulate the muscle stimulation pulse-width required to drive FES-assisted walking gait and the computed motion is visualised in graphic animation from Vn4D and finite state control is used to control the transaction between all walking states. Finite state control (FSC) is used to control the switching of brakes, FES and spring during walking cycle. © 2011 IEEE.

We consider the problem of implementing security algorithms into embedded systems deployed in automation applications. Such systems are typically built on embedded microcontrollers with limited resources and as hardware changes may not be possible or convenient, the software based cryptography is a suitable solution. In this paper we present results of performance benchmarks of different software-implemented symmetric cryptography algorithms on 8 and 16-bit microcontroller platforms. The contribution of the work is in comparing performance of different algorithms, embedded microcontroller platforms, effects of optimizations and different implementations. © 2011 IEEE.

AC induction motors become very popular for motion control applications due to their simple and reliable construction. control of drives based on AC induction motors is a quite complex task. In most high-performance applications classical vector control is currently used. While this control method is usually reliable it has some limitations especially in controllers tuning and constraints handling. In the current paper we present an AC induction machine control method based on model predictive control including field weakening strategy. The proposed control algorithm has been proved and successfully verified in simulation. © 2011 IEEE.

In general, optimal design for the mechanism such as Gough-Stewart Platform (GSP) does not take into account practical factors of the mechanism such as its component weight and size, and mechanical interferences among them, etc. Particularly, in designing a robot module for micro-surgical operations which would be mounted at the end of a macro manipulator, its light weight, compactness, as well as good kinematic performance are important design aspects that should be considered. In this paper, design of a compact GSP module incorporating additional practical design factors such as mechanical interferences among mechanism components is discussed. A modified design for micro-surgical operations which requires a small operation region represented as a nominal operation point is suggested and it is shown that its performance exceeds one of the typical GSP design under the given practical component limitations such as actual length of active prismatic joints. © 2011 IEEE.
