- The Modern Industrial Workhorse: PID Controllers
Proportional-Integral-Derivative PID controllers are used in most automatic process control applications in industry today to regulate flow, temperature, pressure, level, and many other industrial process variables. They date back to , when the Taylor and Foxboro instrument companies introduced the first two PID controllers. All present-day controllers are based on those original proportional, integral, and derivative modes.

It is well-known that PID controllers show poor control performances for an integrating process and a large time delay process. Moreover, it cannot incorporate ramp-type set-point change or slow disturbance. We discuss the above-mentioned limitations of the PID controller. Through the analysis of the limitations, simple techniques are developed to avoid these poor control performances and incapabilities.
We introduce a control structure composed of two PID controllers to manipulate both the set-point change process and the input disturbance rejection process. A simple feedforward and feedback loop are proposed to treat a ramp-type set point and disturbance low-frequency set point and disturbance.
In addition, an internal feedback loop is introduced to incorporate integrating processes, and a tuning strategy using the model reduction is proposed to efficiently tune the controller for high-order processes. A dead-time compensator is used to manipulate a large time delay process more efficiently.

In brief, Proportional, Integral, Derivative PID controller is a feedback controller that helps to attain a set point irrespective of disturbances or any variation in characteristics of the plant of any form. It calculates its output based on the measured error and the three controller gains; proportional gain Kp, integral gain Ki, and derivative gain Kd. The proportional gain simply multiplies the error by a factor Kp. This reacts based on how big the error is. The integral term is a multiplication of the integral gain and the sum of the recent errors.

Some advantages of the autotuning approach in PID control Abstract: The normal approaches to control system compensator design in both classical and modern control first require one to obtain a mathematical model of the process. This is also usually the case even when the form of compensator has been decided and only its parameters need to be found or tuned. This procedure suffers from two disadvantages, firstly the need to find a mathematical model which may be time consuming and not necessarily straightforward, and secondly if tuning in situ is required because the model is poor or its parameters change with time further modelling has to be done or some other approach has to be used. In this paper the theory of the autotuning method is presented and this is followed with a simple example which illustrates the robustness of frequency response tuning.
The Modern Industrial Workhorse: PID Controllers
In control engineering , characterization of a controlled system is primarily determined by its dynamic behaviour which also characterizes the scope and the quality needed to solve a control task. The step response of the controlled system is used to reflect this dynamic behaviour. A controller is one of the most important parts of the control system which measures the performance of the control system. Outputs can be controlled to a particular value or the sequence of events can be performed or an event can also be performed by a control system if the specified conditions of inputs are satisfied. Complex mathematical functions or simple subtraction, addition for comparisons can also be performed by controllers.
As the name suggests, this article is going to give a precise idea about the structure and working of the PID controller. However going into details, let us get an introduction about PID controllers. PID controllers are found in a wide range of applications for industrial process control. These three controllers are combined in such a way that it produces a control signal.
