Data acquisition card and microphone were used to build wood non-destructive testing system based on virtual machines in this paper. Signals of non-destructive vibration experiments was collected and processed by the graphic program of Labview6.1. The dynamic elastic modulus was acquired by the calculation frequency of vibration signals. The static elastic modulus was calculated by the mechanical...
Continuous stirred tank reactor is widely used in polypropylene production with typical nonlinear, time-varying and large time-delay characteristics. In this paper, an advanced control strategy is applied to the continuous stirred tank reactor in which the polypropylene polymerization reaction takes place. On the basis of analyzing the characteristics of polypropylene production process in detail,...
This paper studied the cycle of developing the virtual instrument simulation with GL Studio, simulated the virtual simulation of multi-instruments integrated display panel and driven it by the external data by means of the component-based method. Then it proposes several methods to reduce the resource usage when running the simulation panel. Experimental results show that the proposed methods can...
In this paper the fundamental of the component mode synthesis was reviewed. In order to optimize the ride comfort of the vehicle, a rigid-flexible coupling model of a car was established by using multibody system dynamics method and component mode synthesis technology. The flexibility of the car body, twist beam of the rear suspension, and stabilizer rod was considered. The ride comfort of the vehicle...
Common spatial pattern (CSP) algorithm achieves great success in two-class motor imagery based brain-computer interfaces (BCIs). Low information transfer rate is an intrinsic drawback of binary BCIs that limits their practical application. This paper generalizes the CSP algorithm from two-class to multi-class using a least-squares approach. The multi-class CSP algorithm is implemented by approximate...
This paper proposes an adaptive controller for a free-floating space robot (FFSR) in the presence of friction, disturbance and variation of payload based on robust fuzzy compensator. In the micro-gravity environment, the FFSR lacks a fixed base, so the high dynamic coupling between the manipulators and the free-floating base leads to two inherent difficulties, such as non-linear parameterization of...
Anti-skid Braking Control Box is one of the most important equipments in the aircraft. It is dangerous and costly to modify the parameters of the controller directly. In the paper, a digital aircraft is built, and the velocity-rate-controlled and pressure-bias-modulated control algorithm with balance compensation is used in the Anti-skid Braking Control Box, USB input/output Board exchanges data between...
We investigate approaches to improve the performance of random forests by introducing weight update and bootstrap techniques and propose a new algorithm that combine these techniques smoothly. Experiments show that the proposed approach performs better than the original RF and works well with different weight update techniques used by three most popular version of AdaBoost. At the same time there...
By 1368 sub-samples of general manager changes in 444 Chinese listed companies from 1998 to 2008, this paper used panel LOGIT model to empirically inquiry the impact of corporate Supervisor Board to the mechanism of executive changes and found that supervisor board played an important role in executives changes of listed companies. The stock holding of Supervisor Board had significantly positive correlation...
It is always a hard work to optimize the parameters of auto disturbance rejection controller (ADRC) because of its too many parameters. An optimization method for designing the submarine course ADRC based on the Nonlinear Control Design (NCD) block set of Matlab was proposed. The chief algorithm of ADRC and characters of the NCD block set were referred in briefly too. It was pointed out that there...
