FINAL YEAR PROJECT

PID CONTROLLER

      PID controllers are a family of controller. By using PID, a large number of options will provided. As the options is the number of possibilities for changing the dynamics of the systems. PID controller can gives a better performance that is better than using the proportional or integral alone. There are some tuning methods that available in tuning PID.

      The PID control algorithm is used for the control of almost all loops in the process industries, and is also the basis for many advanced control algorithms and strategies. In order for control loops to work properly, the PID loop must be properly tuned.

PID TUNING METHOD

A well tuned PID controller has parameters which are adapted to the dynamic properties to the process, so that the control system becomes fast and stable. If the process dynamic property varies without re-tuning the controller, the control system gets reduced stability, or becomes more sluggish.

The basic transfer functions of PID controller work as follows:

 The transfer functions of PID controller can also be written as:

STATEMENT OF PROJECT 

      

      In any kind of industries, the usage of an automation systems that doesn’t need many workers to control or supervise the machine eternally. All industries must have their own target of manufacturing their services or products. Due to accomplish their work on time or on the due date, they have to work on it and some equipment sometimes work non-stop. All workers and machines both must work consistently to each other to achieve the company’s target and also to maintain good reputations.

      One of the causes that will cause an accident is overheating on the equipment due to the industries that having an automation system works commonly nowadays. Why must monitoring the temperature? It is important to monitor or control the temperature heat carefully because the extreme temperature will cause a failure to the equipment and systems if the temperature is outside of the operating range. The damage can affect the company budget to the maintenance or replacing the damage or accident that happened. It also may affect the quality time for the company to produce the product and also affect the reputation of the company as well.

      

      In terms of education, nowadays many of higher institutions were built and somehow, the idea of producing the low cost of prototype is to help any higher institutions to get the prototype as additional learning references other than books. So, students can get more knowledge and extra information by getting closer to the real applications before they finished their studies and apply the terms on the real world.
