  • AN122 Introduction to PID Control
    PID controllers are used in most automatic process control applications in industry. They can regulate flow, temperature, pressure, level, and many other industrial process variables. This Application Note reviews the design of PID controllers and explains the P, I, and D. control modes used
  • Implementing a PID Controller Using a PIC18 MCU
    Continuous processes have been controlled by feedback loops since the late 1700's. In 1788, James Watt used a flyball governor on his steam engine to regulate its speed. The Taylor Instrument Company implemented the first fully functional Proportional, Integral and Derivative (PID) controller
  • Optimizing Industrial and Robotic Control Systems Using PID Tuning
    for heavy vehicles, temperature and fluidic systems in manufacturing and refinement processes, and even industrial motion control systems. A century later, the critical impact of PID algorithms is felt by power, industrial, and automation engineers all over the world, giving rise to a new generation
  • PID with Fuzzy Logic Adaptive Control-The Best of Both Worlds
    Proportional integral derivative (PID) control is a well established way of driving a system towards a target position or level. It's practically ubiquitous as a means of controlling temperature, and finds application in myriad chemical and scientific processes as well as automation. PID control
  • Applying Inverters to Centrifugal Compressors in HVAC Chillers (.pdf)
    built-in logic which may be tied into the existing starter. A modification may be required from the chiller manufacturer to allow proper operation with a VFD. You may need to bypass the control logic of the existing chiller and use temperature or pressure feedback and PID to optimize speed control
  • An Innovative Cabling Concept Improves Reliability for Multi-Axis Stage Systems
    driving force, causing an undesirable temperature rise. 2. The bend resistance of the cables is not constant. The result is stick-slip plus randomly distributed effects that make high precision positioning more complicated. 3. Moving cables generate particles and tend to outgas which is undesirable
