will be using aeroquad-s flight control software as a reference point (mostly because it works great and its one of the most used open source flight controllers out there). My flight controller implementation is based on a MK20DX128 chip (found in Teensy 3.0 dev board)‚ there is also an "older" outdated implementation of simple flight controller for ATmega328 (found in many Arduino boards‚ for this implementation i was using Arduino Nano). Step 1.: Hardware and parts Let me start by listing

examples are the toilet bowl float proportioning valve and the fly-ball governor. The proportional control system is more complex than an on-off control system like a bi-metallic domestic thermostat‚ but simpler than a proportional-integral-derivative (PID) control system used in something like an automobile cruise control. On-off control will work where the overall system has a relatively long response time‚ but will result in instability if the system being controlled has a rapid response time. Proportional

proposes and experimentally demonstrates two types of fuzzy logic controllers for an industrial weigh belt feeder. The first type is a PI-like fuzzy logic controller (FLC). A gain scheduled PI-like FLC and a self-tuning PI-like FLC are presented. For the gain scheduled PIlike FLC the output scaling factor of the controller is gain scheduled with the change of setpoint. For the self-tuning PI-like FLC‚ the output scaling factor of the controller is modified on-line by an updating factor whose value is determined

as major field is the next logical step. For the past one and half years I have been working as a in at India. I am working on the commissioning and implementation of Distributed Control System (DCS)‚ Programmable Logic Controllers (PLC) and Conventional PID Controllers in major projects namely ‚ ‚ and . This one and half year stint has given me invaluable practical experience. It has given me the confidence to pursue a MS degree and also kindled a desire to do research. The subject of research

* * Procedures: * 1) Set the Setpoint on the DCS to 50%. Record the PV value it should be near the 50% mark. Now set the DCS Controller faceplate to ‘Auto’ and let it stabilize.Make sure the discharge valve on plant is fully opened. 2) Set P = 30 ‚ I = 3‚ D = 3 as initial values of PID. 3) When stabilize Change the P Value ‚ while maintaining the I and D Values. Note the responses by disturbing the setpoint up or down about 5%.

INTRODUCTION 1.1 In order to be able to build a closed loop controller‚ you need some mean of gaining information about the rotation of the shaft like the number of revolutions executed per second‚ or even the precise angle of the shaft. This source of information about the shaft of the motor is called “feed-back” because it sends back information from the controlled actuator to the controller. 1.2 METHODOLOGY: LASER BASED SPEED SENSOR The methodology of our project is shown
