Grouping parts and tools is an essential problem that arises in the set-up of a flexible manufacturing system (FMS). In the part-tool grouping problem (PGP), the process of assembling parts is assigned to several machines so as to optimize plural performance criteria. In this paper, the PGP is formulated as a multiobjective optimization problem. Then, for sampling various nondominated solutions from along the entire Pareto-optimal front of the PTP, a new genetic algorithm (GA) based on the evolutionary theory advocated by Kinji Imanishi is proposed. While conventional GAs mimic the process of natural selection, the proposed GA realizes the situation of habitat segregation, i.e., a principle of coexistence. The Imanishism-based GA can find various Pareto-optimal solutions effectively, because it keeps the diversity of population in both of the objective and the problem spaces without harming the power of local search operations. The advantage of the Imanishism-based GA is confirmed quantitatively through computational experiments conducted on a practical problem instance of the PGP.

A new method for calibrating the microcontroller based instruments which have no human-machine dialog is presented. The PC is used as an external dialog component for this kind of instrument when performing calibration. By serial communication between the instrument and PC, the instrument's internal settings and parameters for application can be modified easily on the PC. After this method had been used in a practical project, the result showed it has the advantage of high performance and reliability, low cost and is easy to use.

With increasing harmonic pollution in the power system, real-time monitoring and analysis of harmonic variation have become important. A neural networks based approach has been demonstrated to be a very interesting tool for this purpose. However, initial conditions are critical for real-time implementation. A selective harmonic tracking algorithm is proposed to calculate initial conditions for the neural network. In this paper, a fully digital algorithm to measure and evaluate harmonic power using a neural network together with a selective harmonic tracking method is applied to an efficient variable-speed vector-controlled 1.5 kW induction motor drive.

Microelectromechanical systems (MEMS) have a variety of potential civil and military applications. As MEMS become widely implemented, the application of closed-loop control methods to MEMS will lead to higher degrees of certainty and reliability of microelectromechanical operation in physically demanding environments. This paper presents an overview of research and development progress in the area of MEMS control at West Virginia University. The implementation and simulation of a closed-loop stroke-length control of a lateral comb actuator is presented. The closed-loop scheme implemented is based on a common proportional, integral, derivative (PID) linear feedback control. The position signal of the lateral comb actuator device was obtained using a through-wafer free-space optical probe. The paper also includes further progress in both linear and nonlinear feedback position control schemes.

This paper presents the design and construction of a 3-axis manipulator. The paper shows the application of the manipulator to a printed-circuit-board driller system. The manipulator uses direct current motors with permanent magnets. The design of the manipulator is based on microcontrollers to control the speed and position of the motors by using full bridge DC-DC converters with a pulse-width-modulation technique. The designed manipulator includes a personal computer (PC) that works as a user interface to load the file with the numeric control format for the driller. From this information, the PC generates the required position and speed commands for each servomechanism. The paper describes in detail the software and hardware designed to measure and control the speed and the position of each servomechanism.

In the paper two control techniques are compared with respect to the traditional field oriented approach (FO), in order to define the range of applicability of each one. Targets of the different controls are to achieve a vector control and to generate firing commands for the quasi resonant inverter (QRI), that guarantee soft switching of the inverter switch, improving the dynamic response of the whole system. These targets are obtained by means of a state feedback approach.

A self-commissioning algorithm for the determination of the parameters of an induction motor fed by a VSI is proposed. It is based upon the consideration that when the motor is fed by a distorted voltage waveform, in no-load steady state operating conditions, the slips corresponding to harmonics are very near to unity. This circumstance can be exploited in order to perform an evaluation of the motor parameters only by means of a no-load test, provided that an adequate harmonic content of the feeding voltage is imposed. The validity and feasibility of the proposed algorithm are proved by experimental implementation.

This paper deals with rotor position and speed estimation of permanent magnet synchronous motors (PMSMs). Two reduced order observers, a disturbance observer and a nonlinear one, are considered. It is shown that under exact model assumption, the nonlinear observer converges in exponential way, while a residual estimation error appears when a disturbance observer is used. Therefore, uncertainties in the mechanical submodel are taken into account. Estimation error arises due to the mismatch model; bounds for this error are calculated in both observers. Finally, a comparison of the observers performances is presented.

This paper presents an on-chip silicon bulk-micromachined soil moisture sensor (SMS) for irrigation control in greenhouses. The system-on-a-chip includes the SMS, readout electronics, self-test, calibration facilities and a digital bus interface for external data transmission. Moreover, this low-cost device can be applied in several locations (e.g. per each plant root), and networked together with the 1-wire bus. The heat-pulse technique is used (for measuring the maximum temperature on a distant point) to determine the volumetric heat capacity and hence the water content of a porous media, such as soil. In order to validate this method, experimental results were achieved with a macrosensor based on the heat-pulse and capacitance methods. The capacitance method relates the volumetric water content with the capacitance change (dielectric properties) of a probe, inserted in the soil and water contents. These results are compared with the measurement achieved using the conventional thermogravimetric method.
