In this paper, an adaptive attitude control algorithm is developed based on neural network for a satellite using four reaction wheels in a tetrahedron configuration. Then, an attitude control based on feedback linearization control is designed and uncertainties in the moment of inertia matrix and disturbances torque have been considered. In order to eliminate the effect of these uncertainties, ...

Haptic displays serve great importance in creating the immersiveness sense that block Virtual Reality (VR) users from the contradictory impressions from the real world. This paper introduces the general structure of Virtual Reality systems. It reports common approaches in constructing different virtual scenarios and the way they are utilised. The main objective of this project is to integrate a...

This paper proposes an adaptive strategy of co-regulating the three parameters—P/ω droop coefficient, virtual inertia, and damping coefficient—for synchronous generator (VSG). approach is able to solve uncoordinated performance between inertia using conventional control in which system may experience serious frequency fluctuations. Through mathematical modeling VSG grid-connected system, segmen...

Increasingly more power electronic devices are being connected to DC microgrids, which reduces the inertia of a microgrid, and bus voltage has poor resistance disturbance. Adding virtual motor control converter can effectively suppress fluctuation voltage; however, due fixed damping parameters, system cannot attain good dynamic performance. On this basis, two-parameter adaptive is proposed real...

To stabilize the frequency of renewable energy sources (RESs) dominated power system, supports are required by RESs through virtual inertia emulation or droop control in newly published grid codes. Since long-term RES prediction involves significant errors, we need online configure parameters a rolling manner to improve operation economics under premise stabilizing system frequency. address thi...

This article proposes an adaptive coordinated control strategy for the networked AC/DC microgrids (MGs) to enhance frequency and dc voltage stability of system while keeping proper power sharing. First, a based on synchronverter virtual machine (VDCM) converters connecting AC DC MGs is proposed, which consisted governor inertia regulator besides sharing controller. Following, in order performan...
