thanx for the help FvM
my PLC can produce PWM output at any frequenzy. with adjustable duty cycle. so, i think this isn't full wave signal.
mmmm, maybe you can give me some tested circuit about firing phase. that the input is 24volt DC as controler input, and 220volt AC as line power. and the...
thank for all help
now i am understand
Ok, i will change my program and now i will make the PWM switch the power in arbitary phase and automaticaly turn off when the power line in zero crosing. i have try some circuits. i have check my PWM and my Zero crosing detector. i check the ZCD and get...
i have project, and one of the problem is i must drive a heater that use 220VAC/50Hz suply, use PWM signal 24VDC.
i need use the PWM duty cycle to cut the 220VAC phase.
but all circuit that i try to design cant work.
please anyone help me. i need circuit that the input is PWM24VDC and...
T is the sampling time. for example, if you read the input every 2seconds, so T =2. if you read the input every 0,5 seconds, T = 0.5. thats why this equation called "discrete" PID.
i think like that
i have project to make room temperature controler. i use TWIDO PLC and i want to use PID methode. LM35 as a sensor, and heater as the output. and the output signal is the PWM signal. can anyone help me with some example for the PID Algorithm that can aplied on twido. i mean how make the discrete...
i have a project to control a room temperature. i must use PLC and PID algorithm as the methode. in my plan i will use LM35 as sensor and input for the PLC. and heater for the output device. the error temperature will sended as input and feed back for the system. but i have a problem. i dont...
i am new in electronic. i have a project about control system. and first problem is i must make temperature sensor circuit that the sensing output is biner signal. 0 and 1 signal. when the temperature more than 60 Celcius, the output will 1, and when the temperature less than 60 Celcius...
