    PERFORMANCE EVALUATION OF CONVENTIONAL PID CONTROL TUNING TECHNIQUES FOR A FIRST ORDER PLUS DEAD TIME BLENDING PROCESS

    Get PDF
    Dead time is common to real-time processes and occurs when the process variable does not acknowledge any changes in the set-point. This delay may be due to extensive transportation, imprecise instrument calibration and complex non-linearities present at Final Control Element. First Order Plus Dead Time models make the simulations of these processes, tuning of controllers easier and aid in obtaining the most optimum response. Two orders of transfer functions (fourth and seventh) representing blending systems are modelled as First Order Plus Dead Time using the two points method of approximation. A conventional PID controller is used for both the models. In this work, PID control tuning techniques such as Integral of Weighted Time Absolute Error, Internal Model Control, Ziegler-Nichols and Cohen-Coon, are analysed for the optimum design with the aid of time domain analysis. The responses for all tuning methods are simulated using Simulink in Matlab software. The results indicated that Internal Model Control is the best tuning technique in terms of quick settling, minimum overshoots at the initial stages of the response, minimum rise time and minimum amplitude at the peak time, thereby providing most accurate and robust responses for both the orders of transfer functions

    Navigational Strategies for Control of Underwater Robot using AI based Algorithms

    Autonomous underwater robots have become indispensable marine tools to perform various tedious and risky oceanic tasks of military, scientific, civil as well as commercial purposes. To execute hazardous naval tasks successfully, underwater robot needs an intelligent controller to manoeuver from one point to another within unknown or partially known three-dimensional environment. This dissertation has proposed and implemented various AI based control strategies for underwater robot navigation. Adaptive versions of neuro-fuzzy network and several stochastic evolutionary algorithms have been employed here to avoid obstacles or to escape from dead end situations while tracing near optimal path from initial point to destination of an impulsive underwater scenario. A proper balance between path optimization and collision avoidance has been considered as major aspects for evaluating performances of proposed navigational strategies of underwater robot. Online sensory information about position and orientation of both target and nearest obstacles with respect to the robot’s current position have been considered as inputs for path planners. To validate the feasibility of proposed control algorithms, numerous simulations have been executed within MATLAB based simulation environment where obstacles of different shapes and sizes are distributed in a chaotic manner. Simulation results have been verified by performing real time experiments of robot in underwater environment. Comparisons with other available underwater navigation approaches have also been accomplished for authentication purpose. Extensive simulation and experimental studies have ensured the obstacle avoidance and path optimization abilities of proposed AI based navigational strategies during motion of underwater robot. Moreover, a comparative study has been performed on navigational performances of proposed path planning approaches regarding path length and travel time to find out most efficient technique for navigation within an impulsive underwater environment

    Personality Identification from Social Media Using Deep Learning: A Review

    Get PDF
    Social media helps in sharing of ideas and information among people scattered around the world and thus helps in creating communities, groups, and virtual networks. Identification of personality is significant in many types of applications such as in detecting the mental state or character of a person, predicting job satisfaction, professional and personal relationship success, in recommendation systems. Personality is also an important factor to determine individual variation in thoughts, feelings, and conduct systems. According to the survey of Global social media research in 2018, approximately 3.196 billion social media users are in worldwide. The numbers are estimated to grow rapidly further with the use of mobile smart devices and advancement in technology. Support vector machine (SVM), Naive Bayes (NB), Multilayer perceptron neural network, and convolutional neural network (CNN) are some of the machine learning techniques used for personality identification in the literature review. This paper presents various studies conducted in identifying the personality of social media users with the help of machine learning approaches and the recent studies that targeted to predict the personality of online social media (OSM) users are reviewed

    Shortest Route at Dynamic Location with Node Combination-Dijkstra Algorithm

    Abstract— Online transportation has become a basic requirement of the general public in support of all activities to go to work, school or vacation to the sights. Public transportation services compete to provide the best service so that consumers feel comfortable using the services offered, so that all activities are noticed, one of them is the search for the shortest route in picking the buyer or delivering to the destination. Node Combination method can minimize memory usage and this methode is more optimal when compared to A* and Ant Colony in the shortest route search like Dijkstra algorithm, but can’t store the history node that has been passed. Therefore, using node combination algorithm is very good in searching the shortest distance is not the shortest route. This paper is structured to modify the node combination algorithm to solve the problem of finding the shortest route at the dynamic location obtained from the transport fleet by displaying the nodes that have the shortest distance and will be implemented in the geographic information system in the form of map to facilitate the use of the system. Keywords— Shortest Path, Algorithm Dijkstra, Node Combination, Dynamic Location (key words
