Control Methodology

This paper addresses the problem of teleoperation in the presence of communication delays. Delays occur with earth-based teleoperation in space and with surface-based teleoperation undersea using untethered submersibles and acoustic communication links. The delay in obtaining position and force feedback from the remote slave arms makes direct teleoperation infeasible. We are proposing a control methodology, called teleprogramming, which draws on the experience in the development of supervisory control techniques and robotics over the last three decades and introduces a number of new ideas in operator-model interaction as well as the nature and content of the information being sent to the slave robot. A teleprogramming system allows the operator to kinesthetically, as well as visually, interact with a graphic simulation of the remote environment and to interactively, online teleprogram the remote manipulator through a sequence of elementary robot instructions. A key feature and contribution of this work is the fact that these instructions are generated automatically, in real time, based on the operator's interaction with the simulated environment. The slave robot executes these commands delayed in time and, should an error occur, allows the operator to specify the necessary corrective actions and continue with the task. We will in this paper introduce the overall teleprogramming control concept, describe its main components, and report on the preliminary results using our experimental teleprogramming system.

Coordination of various distributed generation (DG) units is required to meet the growing demand for electricity. Several control strategies have been developed to operate parallel-connected inverters for microgrid load sharing. Among these techniques, due to the lack of essential communication links between parallel-connected inverters to coordinate the DG units within a microgrid, the droop control method has been generally accepted in the scientific community. This paper discusses the microgrid droop controller during islanding using the Henry Gas Solubility Optimization (HGSO). The most important goals of droop control in the islanded mode of operation are the frequency and voltage control of microgrid and proper power sharing between distributed generations. The droop controller has been designed using HGSO to optimally choose PI gains and droop control coefficients in order to obtain a better microgrid output response during islanding. Simulation results indicate that the droop controller using HGSO improves the efficiency of micro-grid power by ensuring that variance in microgrid frequency and voltage regulation and effective power sharing occurs whenever micro-grid island mode or when variation in load occurs.
