  • A simple twist unlocks never-before-seen quantum behavior
    Scientists have discovered a revolutionary new method for creating quantum states by twisting materials at the M-point, revealing exotic phenomena previously out of reach. This new direction dramatically expands the moiré toolkit and may soon lead to the experimental realization of long-sought quantum spin liquids.
  • Scientists just recreated a 1938 experiment that could rewrite fusion history
    A groundbreaking collaboration between Los Alamos scientists and Duke University has resurrected a nearly forgotten 1938 experiment that may have quietly sparked the age of fusion energy. Arthur Ruhlig, a little-known physicist, first observed signs of deuterium-tritium (DT) fusion nearly a decade before its significance became clear in nuclear science. The modern team not only […]
  • This breakthrough turns old tech into pure gold — No mercury, no cyanide, just light and salt
    At Flinders University, scientists have cracked a cleaner and greener way to extract gold—not just from ore, but also from our mounting piles of e-waste. By using a compound normally found in pool disinfectants and a novel polymer that can be reused, the method avoids toxic chemicals like mercury and cyanide. It even works on […]
  • Self-lighting chip uses quantum tunneling to spot a trillionth of a gram
    Imagine detecting a single trillionth of a gram of a molecule—like an amino acid—using just electricity and a chip smaller than your fingernail. That’s the power of a new quantum-enabled biosensor developed at EPFL. Ditching bulky lasers, it taps into the strange world of quantum tunneling, where electrons sneak through barriers and release light in […]
  • Scientists freeze quantum motion using ultrafast laser trick
    Harvard and PSI scientists have managed to freeze normally fleeting quantum states in time, creating a pathway to control them using pure electronic tricks and laser precision.
  • Researchers develop recyclable, healable electronics
    Electronics often get thrown away after use because recycling them requires extensive work for little payoff. Researchers have now found a way to change the game.

PID control on PIC microcontroller

For decades, the PID control system has stood as one of the industry's most established and widely adopted strategies, owing to its straightforward yet efficient algorithm. Within this article, we'll delve into the fundamental concept of the PID controller and explore how to imbed it into microcontrollers.

PID tuning methods

Rule-based PID tuning methods asssume that there is a system response that can be put into an easy mathematical description. The  characteristics of this response can be derived from experiments by either putting a step response on an open loop, or by tuning a closed loop system in a certain ...
