Hello
I am writing this post to obtain knowledge about pid, im currently working at some project that includes AVR atmega32 controller controlling 300W heater and i want you to give mi advices where should i look for desired knowledge(books, pdf's, web pages).
One crucial thing that i can not undestand is how can i get a gain of heater that is higher than one when im controlling it by setting amount of sin halves (in example 100% is 100/100 halves, 50% is 50/100 halves - all controlled by triac and optotriac).
How can i find values of kp ki kd coeffs?
And finally, my work is to make this whole controller being able to set a desired temp. value in desired time, how can i implement a desired point setting time?
