PID constant
hi all..
how do I get the Kp, Ki and Kd constant for my dc motor? I am doing close loop speed control using PID method. thanks in advance!!
really thanks davood..
erm.. i m thinking of the forward and reverse regenerative part. Is there any suggestion how to make the motor becomes a generator? Does disconnecting the supply to the circuit a good way to achieve that, with a capasitor(parallel to the power supply) is used to store the...
A schematic is shown in http://www.armory.com/~rstevew/Public/Motors/H-Bridges/Blanchard/h-bridge.htm
Can this circuit be used to do four quadrant operation? This is a full bridge/h-bridge circuit? Can I connect the PWM output from microcontroller to Point A&B to vary the speed without driver...
bridge h regeneration+energy
hi.. thanks!! Mind to share any schematic to do a four quadrant 12V dc motor drive by using full-bridge? I think I am going to use a microcontroller to control the operation and speed of the motor. How to implement PWM? thanks!
pwm circuit schematics
Dear IanP,
For the circuit that u showed me last time, izzit usable for 3-9V dc motor? the current for the motor is arround 0.5A only when no load... so will IRF530 and IRF9530 still applicable? Can I straight away connect pin A and B to microcontroller or I need a...
mosfet pwm circuit
what should i know when buying a dc motor so that i can choose the suitable MOSFETs? power rating or current rating? let say current rating, my MOSFET current rating must be at least the current rating of the motor right? please guide...
thanks a lot!!
merry christmas!! =)
high current pwm schematic
hi! really thanks for the schematic of h-bridge. it is really useful! i am thinking of building this circuit. btw, are the models&values of all the components in the circuit usable for +12Vdc motor? how to determine the model&value of the MOSFETs? really thank you...
pwm pic 16f84
will PIC16F877A be more suitable for PWM dc motor speed control bcz i found that this microcontroller has built in PWM through pin CCP1&2? any external component to be connected to the pins? does it mean that PWM can be generated by the delay function in the programming part? is...
pwm with pic 16f84
thank you very much... nice of u... =)
Added after 23 minutes:
does PIC16F84A still can be used if i want to do a four-quadrant dc motor wif speed control? do the pins enough? thanks
pic16f84 pwm
can u suggest/show me more detail or perhaps example regarding this matter? sorry, this is my first time using microcontroller... thanks!!
