Abstract: PROBLEM TO BE SOLVED: To automatically discriminate whether to apply sliding mode control in a plant from minimum required measured experimental data.SOLUTION: A system first measures a plant in an open control manner and uses the measured data to describe a state equation of the plant in accordance with an existing system identification technique and an order determination method. A switching hyperplane of sliding mode control is designed. Next, regarding a difference between output in the case where only control input of a linear model restricted by the hyperplane is used, and output in the case where control input of a sliding mode is used, a higher-order statistic of a third-order moment and a fourth-order moment are calculated. In the case where a value of the third-order moment is greater than a predetermined threshold value or a value of the fourth-order moment is greater than the predetermined threshold value, a controller is configured as a sum of a linear control input term and a non-linear control input term. In the case where it is determined that both the value of the third-order moment and the value of the fourth-order moment are smaller than the predetermined threshold value, the system uses only the linear control input term to configure the controller.

Abstract: PROBLEM TO BE SOLVED: To automatically distinguish a simplifiable part of system representation by a quantitative reference, in a modeling tool for a design.
SOLUTION: An expression is extracted from a block of SysML, or a block diagram of Simulink (R) is converted into a differential equation, and a coefficient thereof is expanded in a series. First, the differential equation is normally solved by a CAS, and preferably, a solution thereof is also expanded in a series. Next, the expression including the differential equation is solved by the CAS as an interval coefficient by interval analysis technique. Coefficient vectors of the stored solution obtained by performing the normal solution and the solution of a result of the interval analysis are compared. As a result, when an inter-vector distance is a fixed value or below, a target coefficient is set to zero, and the expression including the differential equation is solved by the CAS. The coefficient vectors of the stored solution obtained by performing the normal solution and the solution of the result are newly compared. As a result, when the inter-vector distance is the fixed value or below, a term of the target coefficient is dropped from the differential equation to simplify the differential equation.

Abstract: PROBLEM TO BE SOLVED: To stably separate and extract an original signal from more than one signals by a few calculation steps when the signals in a mixed state are observed. SOLUTION: A function having a monotonous increase characteristic such as an index function is introduced as an evaluating function and the signal is separated by applying an adaptive algorism for minimizing the evaluating function for a signal separation matrix. That is, a signal processor separates the original signal from an observation signal x(t) and outputs it. A non-linear function 21 works with respect to the inputted observation signal x(t) and an estimated separation matrix W(t-1) which is estimated in a preceding cycle and a differential signal e(t) is calculated (22) based on a value y(t) generated by the non-linear function 21, the estimated separation matrix W(t) and the observation signal x(t) at this time. Differential evaluation is weighted by the evaluating function having the monotonous increase characteristic based on the calculated differential signal e(t) and, then, the separation matrix W(t) at that time is updated (23).

Abstract: PROBLEM TO BE SOLVED: To make an input image into halftone without damaging the feature character of an original image and to unnecessitate much arithmetic quantity increase by changing an error diffusion coefficient corresponding to each pixel in the image for each pixel. SOLUTION: A block 230 is provided with an error diffusion filter means, a block 250 is provided with a feature extracting means, a block 260 is provided with a threshold operating means, a block 270 is provided with an adaptive algorithm means and a block 280 is provided with a weight coefficient control means. Then, both feature extracting information and the quantization error information of input/output are provided, while including them with the differential norm of input/output information as a standard and by trading off both the information, a diffusion coefficient is controlled. At controlling of the error diffusion coefficient, a result (v) (n1 and n2) of feature extraction, input information (x) (n1 and n2) and output information (y) (n1 and n2) are utilized. A value λ(n1 and n2) adjusted with respect to each pixel is multiplied to the output, for which threshold processing is applied to a diffusion filter. Thus, the error diffusion coefficient corresponding to each pixel in the image is caused to change for each pixel.

Abstract: PROBLEM TO BE SOLVED: To provide a technique of improving estimation accuracy in an unscented Kalman filter on the basis of nonuniform update timing which considers plant characteristics.SOLUTION: The system achieves nonuniform updates by input to a Kalman filter through an all-pass filter in which a relationship between a numerator polynomial and a denominator polynomial is described as a relationship between mirror image polynomials. Thereby, the input reduces the amount of computation that is different from re-sampling using a polyphase filter. Next, since an estimated quantity of state obtained by the Kalman filter has a nonuniform phase interval if no processing is performed thereon, it is filtered through inverse transformation of the nonuniformity.
