PID controller is a type of controller used to regulate systems. It can be designed for first order systems and its output response can be analyzed.

• PID controller is a feedback control mechanism that continuously calculates an error value and adjusts the control effort to minimize the error.

• It consists of three components: proportional, integral, and derivative, which contribute to the control action based on the error, its accumulation, and its rate of change respectively.

• PI...read more
