I am a college student and i would like to ask you about pid (proportional integral derivative)controller. i had been assigned a project title related to PID controller. my project is to design a hardware and software (c programming) PID controller to control the fuel rate in boiler.
i am going to use temperature as plant. when the temperature is exceed setpoint then feedback to pid controller and thus cut off voltage supply to electrical valve(on off valve). when the temperature is lower then turn on the valve.
but, i am wondering which type of pid controller i should use since i can afford for the lowest price pid controller. and which brand are famous in Asia area? siemens? farnell? please recommend. thanks.
besides, the design of software of PID controller also make me worry since i am poor in programming C. and how can we program into pid controller? using parallel port?
i would to as also how to do the simulation using matlab? what should i concern more based on my project? and is it any method to know the result or the improvement through PID controller? what i meant is how to analyze the process. do i need to know any specific value of the valve, current value, temperaure measurement before plot graph?
has anyone seen the project before in any website? please be kind to tell me. thanks in advance.
sincerely,
peter wong
