There are lots of theoretical research results related to kilowatt-scale Dual-redundancy electromechanical servo system, but the gender gap from the engineering application still remains, and the 10 kw level Dual-redundancy electromechanical servo system belongs to the new technique, which is lack of theoretical and applied research, and the redundancy management technology is one of the key technology...
Based on the power system's stability and control theory, the paper carries out intelligence stability analysis of power system with big data technology. With big data and data mining technology, the paper takes advantage of the useful information from massive data, and makes out the corresponding security and stability of power system intelligent analysis and decision making through the intelligent...
The quick-acting braking is one of the key techniques on dual-redundancy differential actuation system. The permanent magnet brake becomes the preferred option for the dual-redundancy differential actuation system, because of its excellent safety and quick repercussion. The braking and switching mechanism on dual-redundancy differential actuation system is analyzed to identify the influence factors...
In an interconnection, frequency error and interchange power errors on tie lines are two sorts of important indices reflecting the control performance. However, these two indices may be impacted when a DC transmission line is put into operation, or an AC tie line fault occurs. In this paper, a method for evaluating the impacts is proposed, based on the theory of Area Control Error (ACE). First, the...
Considering the response of free charges to high frequency alternating current (AC) electric field and multiemission and capture processes of weakly bound charges, dielectric relaxation effect of free carriers are proposed in this paper. According to this model, free charges and bound charges are regarded as the same except for the difference in transport distance, which is defined by the frequency...
This paper presents the research results on aircraft braking energy recycling and energy management technology. Firstly, this paper analyzes the permanent magnet synchronous motor field-oriented control principle and control method of energy recovery, and then discusses the feasibility of flywheel energy storage and hybrid energy storage technology applied to spacecraft servo system. The results show...
Fluid flowing in ultra-low permeability reservoirs present non-linear characteristics. Based on the equivalent flowing resistance method and superposition principle with flowing field partition principle, non-Darcy flowing model of two phases for overall fracturing combined well pattern with fractured horizontal well and fractured vertical well is established with mutual interference between multi...
The problem of position tracking for a tank gun control system with inertia uncertainty and external disturbance is investigated in this paper. The tank gun control system, demanding high tracking precision and stabilization precision, is a nonlinear system. Classical control methods are commonly used in the actual system, which is difficult to ensure high precision and high disturbance rejection...
Numerical creep analyses on rock salt surrounding repository for high level waste (HLW) are carried out using the software FLAC3D. The results show that the cavity tends to be self-sealed. After near 600 years, the repository space is nearly fully closed and HLW can be kept tightly sealed. Therefore, it is very favorable to build safe repositories for nuclear waste in rock salt formation.
