Advanced yet easy Arduino PID controller with anti-windup, derivative filtering, feedforward, bumpless transfer, gain scheduling and built-in Ziegler-Nichols relay and step-response auto-tuning.
AutoPID is a powerful, portable and fully featured PID control library for Arduino, ESP32, ESP8266, STM32 and AVR boards. It supports automatic millis() timing or user supplied dt, output limits, integral anti-windup, derivative-on-measurement with low-pass filtering, feedforward, setpoint ramping, deadband, gain scheduling, bumpless manual/automatic transfer and automatic gain tuning via Ziegler-Nichols relay and open-loop step-response methods. Ideal for temperature control, motor speed, self-balancing robots, drones, line followers, quadcopters and process control.
