A simple and effective method to determine the region of fractional-order PI<sup>&#x03BB;</sup>D<sup>&#x03BC;</sup> controllers that can stabilize a given fractional-order system with time delay is proposed in this paper. For each known proportional, integral or derivative gain in the PI<sup>&#x03BB;</sup>D<sup>&#x03BC;</sup> controllers, the stability(More)
A new hybrid global optimization algorithm is proposed to search for the global optimum conformation of a given polypeptide amino acid sequences. Consider the limitation of Conformational Space Annealing (CSA) and Cutting Angle Method (CAM), we combine the two methods to enhance the strengths of each algorithm. Firstly, CAM is applied to the generation of(More)
