Series capacitors compensations may cause subsynchronous resonance (SSR) of steam turbine-generators. Using the principle which is depressed SSR by STATCOM and choosing appropriate measured data to design the subsynchronous damping control (SSDC) based on improved particle swarm optimization algorithm which is presented in this paper. Regard the controller parameter of STATCOM as adaptive parameter...
This paper addresses path planning algorithms for an uninhabited aerial vehicle (UAV) based on visibility lines (VL) method for real time applications. VL has been chosen because it provides a solution with optimal path length i.e. minimal distance travelled from starting point to target point. However, as known, the main problem with VL is that the computational burdensome grows exponentially as...
To improve codebook quality in the process of vector quantization, the paper proposes a novel codebook generation algorithm which is based on image segmentation using t-mixture models and greedy EM algorithm. Additionally, in the initial codebook generating procedure, the PNN algorithm is used to reduce LBG algorithmpsilas sensitivity to initial codebook. Experimental results show that the proposed...
