Outlier detection is an important procedure in industrial dataset preprocess to guarantee the industrial process operating normally. This paper proposed a new local density definition in the basis of the minimum hyper sphere for outlier mining algorithm. First, the novel local k-density definition of an object is proposed by using the minimum enclosing hyper sphere algorithm. After this, the new k-density...
Submerged arc furnace is a system with strong coupling, nonlinearity and time-variability. In this paper, a logistic-interpolation-based fuzzy controller for electrode regulation of submerged arc furnace is proposed. The proposed controller is based on fuzzy logic control strategy, and interpolation algorithm is employed to improve the control accuracy without raising complexity of the controller...
This paper investigates the sliding mode control of three-phase voltage source PWM rectifier (VSR). When the three-phase VSR system is applied in different environmental conditions, external disturbances are inevitable and stochastic, so these conditions should be taken into consideration when designing the controllers. To have a good performance and a fast response, the whole closed loop control...
In order to analysis the energy saving from the fluid power, This paper gives out the concept of generalized vacancy waste. By introducing two examples, Empicical results show there is no any energy saving if water overcome lift and friction in water supply system, and point out that there will be energy saving if the parameter of VVVF is setting correctly.
Hybridization is a useful method to enhance the performance of particle swarm optimizer (PSO). In this paper, a novel particle swarm optimizer (NHPSO) combining PSO with a constriction factor (CF-PSO) and the fully informed particle swarm optimizer (FIPSO) in cycles is proposed, in order to balance the convergence speed and search accuracy. Six most commonly used benchmarks are used to evaluate the...
