Position control for linear motion servo system via nominal characteristic trajectory following controller

Motion control system is a challenging problem in the area of control systems. It is very useful to demonstrate concepts in linear control such as the stabilization of unstable systems. Motion control system plays important roles in industrial equipment such as machine tools, semiconductor manufacturing systems and robot systems. One type of motion control systems is point-to-point (PTP) positioning system, which is used to move an object from one point to another point. Linear motion servo system is a machine that move cart from one point to another point. This system consists of a cart driven by a DC motor, via a rack and pinion mechanism to ensure consistent and continuous traction. Up to now many types of controllers have been proposed and evaluated for positioning systems. Two type of controller that discussed in this thesis are Proportional-Velocity (PV) and Nominal Characteristic Trajectory Following (NCTF). The experimental results showed that the PV was successfully implemented which controlled the settling time, rise time and steady-state error of the desired position. However, the overshoot performances show its disadvantages. Additionally, the PV controller design is time consuming process, since model and parameters of the linear motion servo system are needed. Therefore, the needs for higher performance controller become important for the simplicity of the controller design. Hence, the investigation proceed with the non-model based NCTF controller was to control the cart position of the linear motion servo system. The NCTF controller consists of a Nominal Characteristic Trajectory (NCT) and PI compensator. The NCTF controller was designed based on a simple open-loop experiment of the object. The experimental results showed that the NCTF controller is more effective for controlling position oflinear motion servo system than the PV controller

Development of Nanocomposite Polymer Electrolyte Membranes for Higher Temperature PEM Fuel Cells

Proton exchange membrane (PEM) fuel cells are one of the most promising clean energy technologies under development. The major advantages include electrical efficiencies of up to 55 %, high energy densities (relative to batteries), and low emissions. However, the main obstacles to commercialization of PEM fuel cells are related to the limitations of the proton conducting solid polymer electrolytes such as Nafion. These membranes are expensive, mechanically unfavorable at higher temperatures, and conduct protons only in the presence of water, which limits the fuel cell operating temperature to about 80 C. This in turn, results in low fuel cell performance due to slow electrode kinetics and virtually no CO tolerance. The potential operation of PEM fuel cells at higher temperature (above 100 C) can provide many advantages such as improved kinetics at the surface of electrode, which is especially important in methanol and CO-containing reformate feeds, and efficient heat rejection and water management. Another issue above 100 C is the reduction of electrochemical surface area of the electrodes due to shrinkage of electrolyte (Nafion phase) within the catalyst layers. This research work is thus focused on the development of nanocomposite proton exchange membranes (NCPEMs) which are chemically and mechanically more stable at higher temperatures and electrodes which can result into better fuel cell performance. These are composite materials with inorganic acidic nanoparticles incorporated within a host polymer electrolyte membrane such as Nafion. The target operating fuel cell temperature in this work is above 100 oC with relative humidity around 30 to 40 %. To achieve these targets, both theoretical and experimental investigations were undertaken to systematically develop these NCPEMs. Various experimental techniques, namely, TEOM (Tapered Element Oscillating Microbalance), Impedance Spectroscopy, MEA (membrane electrode assembly) testing, Ion Exchange Capacity, Scanning Electron Microscope (SEM), Optical Electronic Holography (OEH), Thermal Gravimetric Analysis (TGA), and Dynamic Mechanical Analysis (DMA) were employed to characterize the NCPEMs. A thermodynamic model was developed to describe sorption in proton-exchange membranes (PEMs), which can predict the complete sorption isotherm. A comprehensive proton transport model was also developed to describe proton diffusion in Nafion/(ZrO2/SO42-) nanocomposite membranes. The conductivity of the in situ sol-gel prepared Nafion/ (ZrO2/SO42-) nanocomposite membranes was accurately predicted by the model as a function of relative humidity (RH) without any fitted parameters. This transport model developed offers a theoretical framework for understanding the proton transfer in nanocomposite membranes and is an insightful guide in systematically developing high proton-conducting nanocomposite. Nafion-MO2(M = Zr, Si, Ti) nanocomposite membranes were synthesized with the goal to increase the proton conductivity and water retention by the membrane at higher temperatures and lower relative humidity (120 C, 40% RH) and also to improve the thermo-mechanical properties. The results obtained are promising and indicate that this is a potentially useful approach for developing PEMs with desirable properties. Finally, commercially available high temperature PBI (polybenzimidazole)-H3PO4 (phosphoric acid) gel membrane fuel cell was investigated in the temperature range of 160-180 C. This system exhibited very good and stable performance in this temperature range

EFFECTS OF EXAMPLE-PROBLEM BASED LEARNING ON TRANSFER PERFORMANCE IN CIRCUIT THEORY

The main goal of the study was to test a hypothesis that Example-Problem-Based Learning (EPBL) would lead to better transfer performance compared Traditional Learning (TL) approach.  The participants were vocational diploma-level students and the learning domain was Circuit Theory. As a means of data collection, 10-items open-ended test (five items each for assessing near-transfer and far-transfer) was administered as a pre-test and post-test. A sufficient reliability estimate was obtained, a= 0.74, based on the Cronbach Alpha method. A statistically significant difference on the post test score was observed between the EPBL and the TL group where the EPBL group scored higher than the TL group on both near and far-transfer.  In conclusion, EPBL approaches produces greater learning compared to TL approach, for both near and distant-transfer
