To achieve the control of movement speed stability and location accuracy of two-dimensional motion platform, considered the movement characteristics of sliding table drive motor, a motion control method based on servo motor encoder feedback signal is proposed in this paper. By using real-time emulation platform of XPC target and related peripheral circuit, completed the construction of the motion control system. By analyzing the experimental data, proved the two-dimensional motion platform control system based on xPC target operation stable, meet the position control accuracy, motion response rapidly, and easy to adjust the control parameters requirements, and own high engineering practical value.

Target Platform

The goal of this work is to describe a control procedure that simplifies the implementation and improves the performance of feedback active control on a planar structure. The article presents a design, development and experimental verification of an active feedback vibration control system of circular plate with the application of xPC Target platform. Vibrations of the plate are measured using MFC sensors. The control input is applied to the plate by a MFC disk, attached to the plate in its center. The plate vibrations were excited by a loudspeaker or by a second MFC actuator placed at a certain distance from the center of the disc.The basic philosophy is the off-line identification of the best model for the controlled process [1] and the subsequent synthesis of the controller. There are many classical strategies that can be used when a mathematical model is available, for instance, poles allocation or optimal control (LQR), used also by the authors [2, 3]. This article proposes an approach to design an effective controller for vibration suppression of a circular plate with the use of the pole placement method. For the considered system a linear discrete model obtained by parametric identification method for the data measured in a separate experiment has been designated. This model was used to develop the 6-th order digital controller which was implemented on xPC Target platform. Before implementation of the chosen control law design on real plant the simulations in Simulink/Matlab were performed. In order to investigate the influence of the implemented controller on the plate vibrations suppression the 3D scanning vibrometer has been used. The obtained simulation and experimental results, corresponding to the developed active vibration control system have been presented, compared and analyzed.

The paper presents a system controlling ship motion at low speed. The control system makes use of three fuzzy logic controllers. They are: course keeping controller, longitudinal position keeping controller and transverse position keeping controller. Three controllers work independently to keep the ship hull centre at the reference point with the set course. The ship motion is controlled by tracing and following coordinates of the reference point. They change according to the assumed ship motion trajectory and speed. The ship control system use three propellers: bow thruster, stern thruster and the main propeller of the ship. The control signals (propellers powers) have the form of pulses with relevant amplitude and time duration. The pulsatory nature of the control signals was obtained by proper selection of the shape of the member functions in Mamdani-type controllers and the use of the bisector defuzzyfication method. The magnitude of the signal is changed in steps and plays the role of rough control while its duration is adjusted continuously and plays the role of fine control The control system was worked out in Matlab-Simulink with RTW, xPC-target toolboxes and tested on a scaled physical model of a tanker in the real lake environment. The system installed on model contain two PC computers and as the measured devices use DGPS RTK Leica system, ST20 Anschutz gyrocompass and Gill-windobserver. The paper discuss the controlling algorithm, along with the results of control system tests.

Response Method

This paper presents the process of a motion control system design and implementation for a teleminulation system. The robotic manipulator/hand is a nonlinear system with coupled effects among the joints. By applying the frequency response method, the nonlinear system is modeled as decoupled linear ones, in which each joint is controlled independently. The experimental results show the feasibility of the modeling process. Based on the obtained transfer function of each joint, the digital PID controllers are designed. The motion control system for the telemanipulation system is then implemented using the software package MATLAB, Simulink, Real Time Workshop, xPC Target and a C/C++ compiler, and the hardware I/O boards, amplifiers, etc. The presented developing procedure shows a convenient way to implement a real time robotic control system.

Main Components

LaB6 emitters are becoming increasingly popular as direct replacements for tungsten filaments in the electron guns of modern electron-beam instruments. These emitters offer order of magnitude increases in beam brightness, and, with appropriate care in operation, a corresponding increase in source lifetime. They are, however, an order of magnitude more expensive, and may be easily damaged (by improper vacuum conditions and thermal shock) during saturation/desaturation operations. These operations typically require several minutes of an operator's attention, which becomes tedious and subject to error, particularly since the emitter must be cooled during sample exchanges to minimize damage from random vacuum excursions. We have designed a control system for LaBg emitters which relieves the operator of the necessity for manually controlling the emitter power, minimizes the danger of accidental improper operation, and makes the use of these emitters routine on multi-user instruments.Figure 1 is a block schematic of the main components of the control system, and Figure 2 shows the control box.
