Auto Tune Issue 200 Pid

| Posted on by

Jun 23, 2013 Good day sir,I am using S7-200 PID for the first time and i am facing problem in implementing it. My application is very simple and for testing of PID only i prepared a test program which is attached.I have a pump with VFD operated. Getting Started. Welcome to the TH3D P.I.D. Auto Tuning Guide! This will take you through the steps to P.I.D. Tune your printers hotend. If you have the new Unified Firmware you can go to Control Temperature PID Autotune Then set to 240 if you have a stock hotend and 250 if you have an all metal. 8.1.3 Extruder cannot reach temperature. Do you have an extruder on a dual extruder printer which cannot seem to reach temperature during a dualstrusion print? You may be able to resolve this with a change to the PID parameters for the extruder in question. This problem is particularly common on Replicator 2X printers manufactured during or after October 2013.

This project has been created to support tuning a PID controller for a home brewing setup using CraftBeerPI.It consists of a brewing kettle simulation, a PID controller (based on Arduino PID Library) and a PID autotune algorithm (based on Arduino PID Autotune Library)

Project goals

  • allow users to find PID parameters which provide a sufficient basis for further manual tuning
  • allow users to compare different PID parameters
  • help users to understand how different PID parameters (Kp, Ki, Kd) influence a PID controller's behavior (not only limited to home brewing setups)
  • speed up auto tuning

PID comparison

Compare different PID parameters using the default kettle setup:
sim.py --pid 'reference' 98 0.66 230 --pid 'Kp too low' 30 0.66 230 --pid 'Ki too low' 98 0.01 230

Simulate a PID autotune run on a 50l kettle with a 4 kW heater:
sim.py --atune --volume 50 --power 4

Generated PID parameters using different tuning rules:

Options

Tune
  1. Install git and python3
  2. Clone this repository:
    git clone https://github.com/hirschmann/pid-autotune.git
  3. Install project dependencies:
    pip install matplotlib

After you have completed these steps, you should be able to run sim.py as shown above. If plots are not shown, you have to configure the matplotlib backend, see What is a backend?
