This paper presents the design and the implementation of two control solutions applied to a magnetic levitation system laboratory equipment. The first solution deals with a state feedback control structure to stabilize the controlled plant which is the inner control loop for the cascade control system structure proposed as the second solution. The second solution is based on a Takagi-Sugeno fuzzy controller in the outer control loop to ensure the zero steady-state control errors. Simulation and real time experimental results are included to illustrate the performance of the control systems and to validate the two control solutions in regulation and tracking.

This paper proposes a platform referred to as nDSP to interconnect different software audio signal processing effects which are modularized. The new platform is focused on having all processing done by the system CPU at higher quality than that achieved using hardware DSPs. The software representation of the module inside the platform is defined such that its state can be externally controlled, therefore the design of self-tuning filters is allowed. The design aims the further use of software audio signal processing in low-cost audiophile loudspeaker systems taking full advantage of the new personal computer hardware products.

In this paper, we demonstrate the usefulness of the micro-manipulation system with a robotic straw proposed by the authors for the microorganism isolation task. Isolating microorganism is one of the fundamental bio-manipulation tasks. This task has been conventionally achieved with a straw connected with a rubber tube. However, some skill is required by an operator for this isolation task, because it is difficult for a naive operator to place the tip of pipette at a desired position under a microscope. We show that the microorganism isolation task is successfully achieved with the proposed system even by a naive operator of the conventional microorganism isolation task without long-term training. ©2010 IEEE.

The paper presents aspects concerning the modeling and driving scenarios of a class of vehicular power train systems. The modeling includes an analysis of the system components which include the spark-ignition internal combustion engine, the torque converter, the metal V-belt type continuously variable transmission and the wheels. Four driving scenarios are illustrated by digital simulation results: acceleration, overtaking maneuver, ramp encounter and engine brake.

Corotational nonlinear finite element formulation and modeling of electrostatically actuated microbeams

A complete nonlinear finite element model for coupled-domain microelectromechanical system devices with electrostatic actuation and squeeze film effect was developed. for this purpose, a corotational finite element formulation for the dynamic analysis of planer Euler-Bernoulli microbeams considering geometrical nonlinearities due to both large structural deformation and electrostatic actuation is developed. In this method, the internal forces due to deformation and residual stresses, the elemental inertias, and the damping effect of the squeeze-film are systematically derived by consistent linearization of the fully geometrically nonlinear beam theory using d'Alembert and the virtual work principles. An incremental-iterative method based on the Newmark direct integration procedure and the Newton-Raphson algorithm is used to solve the nonlinear dynamic equilibrium equations. Several numerical examples are presented and their results are compared with those found experimentally, which indicate a very close agreement. © 2009 SAGE Publications.

In this paper, we propose a novel master-slave system for micro-manipulation of the mechanical contact type. In the proposed system, suck and blow movements in the master side are scaled and transmitted to the slave side, i.e., we generate the air flow at the tip of the micro-straw in the slave side according to operator's suck and blow in the master side. The air flows by operator's suck and blow are detected by a series of two flow sensors opposite in direction each other. The output air flow at the micro-straw is controlled by switching a series of two solenoid valves whose three inputs are connected to an air compressor, a vacuum pump, and the atmosphere respectively. The switching law is calculated based on the data from the flow sensors. Moreover, by vibrating the straw at an operator's mouth according to the detected contact between the microstraw and a micro-object, we also expect immersive feel as if the operator sucks or blows the micro-object directly with the straw. The suck-and-blow master-slave system proposed here is compatible with the master-slave system based on the body image embedding the authors proposed previously. By combining the two systems, we expect to realize the rapid pick-and-place in a micro-world. We show some results on very basic experiments, i.e., measurement of air flows by operator's suck and blow, and picking a micro-particle by suction, to prove the potential of the proposed micro-manipulation system. ©2009 IEEE.

IEEE International Workshop on Robot and Human Communication (ROMAN)

In this paper, we propose a novel macro-micro tele-manipulation system based on body image embedding with contact feel, spatial motion and stereo vision for micro-manipulation under a microscope. The basic concept of body image embedding for macro-micro tele-manipulation has been already proposed by the authors. The system proposed here has three new realization ideas. The first idea is the realization of realistic contact feeling which is attained by driving a voice coil motor according to the binary on/off information of the switch between micro-tools. The use of a voice coil motor not only saves the cost of the system, but also generates clearer tactile and auditory stimuli than a piezo actuator for sending contact information in a micro world to an operator. The switch between micro-tools does not detect the contact between the object to be manipulated and the tool for manipulation directly, but can be useful for some tasks. The second idea is the realization of spatial motion of the manipulation tool relative to the object to be manipulated, which is realized by the appropriate coordination of the 2-degree-of-freedom motions of the slave manipulators. The third idea is the realization of stereo vision under the constraint of the position/orientation consistency of an operator's body image between proprioception and vision, which is achieved by the special placement of the dual joysticks of the dual micro-manipulators. The effectiveness of the proposed realization method is verified experimentally by micro-drawing tasks where we need appropriate hybrid position/force control of the micro-tool for manipulation in a three-dimensional space.
