In the visual servo control of the manipulator with the hand/eye system realizing the stable convergence to target feature points with visual distortion, it is necessary to control not only the tip position but also the direction of the hand/eye system. To control both motions at the same time, the redundant manipulator is useful. In the proposed method, the rotational motion is controlled by null space input to reduce the visual distortion. Furthermore, to realize the stable motion convergence, the null space input gain is adjusted by fuzzy logic. To confirm the validity of the proposed method, simulation and experimental results are shown.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

In this paper a novel method for solving nonlinear equations in preprogrammed PWM Inverters is presented. The starting values for solving the nonlinear equation, are derived from the equal area algorithm. This method guarantees convergence in a numerical solution for solving nonlinear equations so that the trial-and-error processes can be significantly reduced. The numerical solutions for nonlinear equations for a full range of the fundamental amplitude can be easily obtained. Thus, this method makes fundamental amplitude modulation feasible and is helpful for online control. The output pattern of the proposed programmed PWM technique is superior to the equal area algorithm in harmonic attenuation since this technique eliminates the specified harmonics. The experimental results are used to verify the performance of the proposed scheme.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

It is proved that the scheduling problem belongs to the class of NP-hard problems. For the scheduling problem, the authors have already proposed two algorithms: one is a heuristic approach and the other is based on branch-and-bound approach. These conventional algorithms, however, have the limits of their ability in quality of solutions and computational time. The scheduling problem is a typical partitioning problem: partitioning N objects into P groups to optimize an objective function. Therefore, each feasible solution is represented by a way of division of a suffix set (1,...,N) into P subsets. In the proposed GA for the scheduling problem, such a feasible solution is regarded as a phenotypic individual. Then this paper proposes a new phenotype based crossover operation named \"weighted-edge crossover\". By using the proposed crossover, a child inherits the desirable characteristic from both parents, keeping its structure as a feasible solution. Furthermore, in order to improve the performance of the crossover operation, this paper proposes a distance function between phenotypic individuals and uses it in the adaptive control of crossover rate. To demonstrate the efficiency of the proposed GA, comparative study with the conventional algorithms is carried out on several experiments.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.

The adaptive current controller, which operates in the stationary two-axis frame to provide the persistently exciting condition for parameter estimation convergence, consists of a one-step-ahead predictive controller and a model estimator. The predictive controller's parameters are adjusted adaptively on line in terms of estimated model parameters. Estimating the model parameters entails a first-order four-dimensional least-squares estimator with exponential data weighting to detect the variations of the motor parameters and the back EMF. The proposed adaptive control scheme is implemented in parallel by IMS T800-20 transputers. Simulation results show the effectiveness of the proposed adaptive current control scheme.","PeriodicalId":404447,"journal":{"name":"Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat.
