In this work, the particle swarm optimization (PSO) algorithm combined with chaotic theory was employed to modeling data of biochemical systems. For this purpose, three case studies will be applied with PSO as parameter estimation problems and examine the performance of the new developed methodology.
In this paper, we study robust stabilization of commensurate fractional order interval polynomial with the PID controller. In this paper, we show that a special class of commensurate fractional order interval plants can be stabilized by PID compensator if some of edge characteristic polynomials can be stabilized by the PID compensator. The proof is based on the fact that the special commensurate fractional...
In this paper, we show that a special class of commensurate fractional order interval plants can be stabilized by proportional compensator if some of extreme plants can be stabilized by the compensator. The special class of commensurate fractional order interval plant means that both its numerator and denominator polynomials has the orders whose values are the multiples of the irrational number between...
This paper deals with robust stability of a diamond-type of commensurate fractional order polynomials. The diamond-type of commensurate fractional order polynomials means the uncertain commensurate fractional order polynomials of which coefficients lie in a diamond type of boxes. In this paper, we show that robust stability of a diamond-type of the commensurate fractional order polynomials is robustly...
This paper deals with robust stability of commensurate fractional order interval polynomials. Tan et al. obtain the robust stability result of fractional order interval polynomials. The result is that the fractional order interval polynomial is robustly stable if and only if all the exposed edge polynomials are robustly stable. In this paper, some simplification is presented for robust stability of...
In this paper, we consider robust stability of interval polynomials of which stability region is the special left sector. The argument of the boundary of the special left sector is expressible as an irrational number multiplied by the circle ratio. We show that a family of interval polynomials is robustly stable if and only if a small set of vertex polynomials are robustly stable. This new result...
In this paper, we develop the path planning algorithm using the improved Dijkstra algorithm and the particle swarm optimization. To get the optimal path, at first we construct the MAKLINK on the world environment and then make a graph associated with the MAKLINK. From the graph, we obtain the Dijkstra path between the starting point and the destination point. From the optimal path, we search the improved...
This paper proposes the hybrid simplex algorithm (SA)-harmony search(HS) Method. HS method is, the evolutionary algorithm, conceptualized using the musical process of searching for optimization problems. SA helps HS find optimization solution more accurately and quickly. In this paper, the performances of proposed algorithm are compared with the original HS method and other algorithms through unconstrained...
Palm-print recognition is recently emerged as new personal verification for reliable identification and alternative for latent comparison of unsolved cases for suspect criminals in forensic science. This paper deals with comparison of live palm-print using sub image divided from the whole image by capturing of high resolution live scanner. Proposed method is very robust and accurate with live sample...
In this paper, we focus on the optimization of fuzzy clustering. Particle swarm optimizations (PSO) is used for optimizing the algorithms. PSO is an algorithm which takes a cue from nature's bird flock or fish school and is known to have superior ability in search and fast convergence. But it might be difficult to find global optimal solution of the fuzzy clustering when it comes to complex higher...
In this paper, we propose the estimation method for the image affine information for computer vision. The first estimation method is given based on the XYS image normalization and the second estimation method is based on the XSR image normalization. In addition, we show that rotation and aspect ratio information can be obtained using the central moments of both the original image and the sensed image...
