In control theory, Quantitative Feedback Theory (QFT) developed by Issac Horowitz, has gained a lot of popularity. Many researchers have proposed a method to generate the bounds that from the literature it is observed that generation of bound takes a lot of time for online design of the controller. It is necessary to speed up the computation of bound generation. This paper exhibits the parallel computing power of the GPU (Graphics Processing Unit) in the area of QFT. In this paper, GPU based approach is proposed to speed up the computation of stability bound. By using MATLAB parallel computing toolboxes, GPU computational power can be easily accessed with the minimum knowledge of GPU architecture, MATLAB code can be executed on the GPU. In order to achieve faster execution of QFT bound generation, NVIDIA GPU with the support of MATLAB parallel computing toolbox is used in this work. Performance comparison of the algorithm for sequential implementation on CPU and parallel implementation on GPU is carried out. This work analyzes the relative performance of GPU vs CPU. In this paper, GPU based approach proposed for significant speedup in the computation of bound using QFT and it is observed that GPU provides speedup two to three times as compared to the CPU.

Important Announcements

All the authors, conference coordinators, conveners, and guest editors kindly check their articles' originality before submitting them to IJCERT. If any material is found to be duplicate submission or sent to other journals when the content is in the process with IJCERT, fabricated data, cut and paste (plagiarized), at any stage of processing of material, IJCERT is bound to take the following actions.
1. Rejection of the article.
2. The author will be blocked for future communication with IJCERT if duplicate articles are submitted.
3. A letter regarding this will be posted to the Principal/Director of the Institution where the study was conducted.
4. A List of blacklisted authors will be shared among the Chief Editors of other prestigious Journals
We have been screening articles for plagiarism with a world-renowned tool: Turnitin However, it is only rejected if found plagiarized. This more stern action is being taken because of the illegal behavior of a handful of authors who have been involved in ethical misconduct. The Screening and making a decision on such articles costs colossal time and resources for the journal. It directly delays the process of genuine materials.
