In this thesis, a new control algorithm iterative learning control (ILC) is applied in the force load control for fatigue testing machine due to non-linearity and unmodeled character of electro-hydraulic servo system and repeatability of fatigue testing machine. A model is established to describe electro-hydraulic servo force control system. According to the model, a controller based on ILC is designed...
Aimed at the disadvantage of current research of shill bidding with different online auctions types, in this paper, Applying decision analysis method and game theory, firstly, we research the bidder's optimal biding Strategy on English Auction, First-price Sealed-bid Auction and Second-price sealed-bid auction with Shill Bidding, respectively. Secondly, we use bidder's expected gain and seller's revenue...
By constructing the exponential delay cost function, we formulate the consumer decision model based on the threshold strategies in dual-mechanism, and prove that there exists a unique symmetric Nash equilibrium in which the high-valuation consumers use a threshold policy to choose between the two selling channels. Then we extend our model under general delay cost function, and find that consumers...
Based on the sinusoidal pulse width modulation technology and regular sampling method, the switching time points calculation formulas of tangent method and secant method are established. This paper analyses the precision of switching turn-on and turn-off time point, and compare these switching time points. Calculation results show that SPWM pulses generated by tangent method and secant method are...
Most of the reported Distributed Video Coding (DVC) schemes have a high time-delay in decoder which hinders its practical application in real-time systems. In this paper, we propose a new DVC decoder architecture based on MPI clusters and an efficient parallel algorithm for generation of the Side Information (SI) based on the structure. In order to achieve a balanced workload among the processors...
The synthesis control of force and position in electro-hydraulic servo system has been applied to some special occasions. Analyzed a typical system which adopted this kind of control algorithm. Applying unchanged structure theory, the compensated transfer function has been deduced, the compensated state-space model is presented. Considering the synthesis control should meet the requirement to force...
The double revolving-field theory is found not to comply with the superposition principle of magnetic fields. A vector expression is proposed to describe the single traveling field wave formed in air-gap by pulsating fields produced by stator windings.
