A Single tank level control system has one rectangular tank which has inflow of liquid into the tank and out flow through valve. The control System is intended to maintain the level of liquid in the tank at some predefined value irrespective of changes inflow of tank. Conventional PID controller gives better results due to changes in load. Thus change in inflow or changes in predefined values are treated as disturbances to the process. According to these disturbances we need to implement better tuning algorithms to PID controllers. But industrial conventional PID controllers exhibits nonlinear output for the given error values. Thus the approach of non linear PID controller is to include the disturbance parameters to conventional PID controller. The behavior is observed with step input. In this paper we implemented different non linear PID control algorithms on tank level control System and their responses are observed.
In this paper, Traffic Light Controller using Arduino is designed and experimentally tested. The proposed Arduino Traffic Light Controller Project is simple and can be easily understood. Here we have demonstrated Traffic lights for the 3 ways road and the code glows LED"s on all the three sides in a particular sequence, in which the actual Traffic Lights works.
In this paper, RFID based Door access control using Arduino is based upon security access and control system using RFID and Arduino. The embedded chips in RFID use radio signals to capture and read information on the object. Barcodes labels have been in the industry for over more than 30 years but over a past decade, new technologies like Radio Frequency Identification (RFID) have diminished the luster of barcodes. RFID technology is significant and consistent means to identify the material. Arduino helps to design the circuit and makes programming a lot easier to understand.
Robot controlling through Wi-Fi is a fascinating tool to operate laboratory experiments within Electronics and Telecommunication Engineering. Designing of the system requires the expertise of physical components, sensors, embedded system and selection algorithm. As we know people can't perform many tasks which a Robot can do. Robots are required where human interventions are nearly impossible. Due to this, a thinking of designing a robot which can be controlled via Wi-Fi emerged in our minds. Here controls of the robotic are built-in on a webpage. This undertaking involves of basically the following modules Wi-Fi Module, Router, Microcontroller and Smartphone and laptop with which handles all simple functionalities of a Robot.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
