PID controller

In this study, the PID controller design method based on direct synthesis approach for achieving the desired set-point or load-disturbance response is proposed. The PID controller is derived using an approximate frequency-response-matching criteria. A simple criterion has been also provided to choose the frequency points for matching of the proposed PID controller with the desired direct synthesis controller. It is a unified approach which deals with broad class of processes including integrating and inverse response, and it is directly applicable to any order of process with time delay. The ideal controller based on the direct synthesis approach has been directly approximated to the PID controller in desired frequency range. The advantage of method is illustrated through examples taken from the literature and compared with some of the well-known methods.

A proportional—integral—derivative controller PID controller or three-term controller is a control loop mechanism employing feedback that is widely used in industrial control systems and a variety of other applications requiring continuously modulated control. In practical terms it automatically applies an accurate and responsive correction to a control function. An everyday example is the cruise control on a car, where ascending a hill would lower speed if only constant engine power were applied. The controller's PID algorithm restores the measured speed to the desired speed with minimal delay and overshoot by increasing the power output of the engine. The first theoretical analysis and practical application was in the field of automatic steering systems for ships, developed from the early s onwards. It was then used for automatic process control in the manufacturing industry, where it was widely implemented in pneumatic, and then electronic, controllers.

A control system which has become commonplace in the automotive industry is the cruise control system: an output is programmed by the driver, and the control system has to manage all of the vehicle readings in order to maintain velocity. Before solving for a system, we will briefly analyze the components and behavior of a system uncompensated and then the individual components of a PID proportional-integral-derivative controller. The final step would be to bring these two together and design a PID controller that will compensate the originally observed system. It is important to know that PID controllers are not the only type of compensation a designer can apply to system, but it's a great place to start and learn some of the universal characteristics that will stay true in other methods. A system can be made up of various components arranged in equally various ways; but we will begin by analyzing the components and functionality of a classical closed-loop sytem Figure 1.

Nowadays, many of control systems need a flexible controller in order to achieve the operation requirement precisely and rapidly to overcome nonlinearity, uncertainty, digital implementation challenges, and achieving at the same time both of control system objectives of load disturbance rejection and set point following. This paper is aimed to design and analysis one of the most common industrial controllers, set point weighting 2DOF PID controller, to get this target with simplicity and effectiveness.

Ang, K. Designing and tuning a proportional-integral-derivative PID controller appears to be conceptually intuitive, but can be hard in practice, if multiple and often conflicting objectives such as short transient and high stability are to be achieved. Usually, initial designs obtained by all means need to be adjusted repeatedly through computer simulations until the closed-loop system performs or compromises as desired.

Arzabala-Contreras 3. Today control is required in any field or application. Nowadays, classic control is the most used, but it is well-known that users need to know the system's characteristics to reach optimal control. This paper is focused on designing a proportional integral derivative control, based on a single artificial neural network with the aim to improve its performance and its use with minimal control knowledge from the end user. The proposed control was assessed with simulated and practical physical systems of first and second order. In order to increase the confidence of the intelligent sensor control, the evaluation was made using the classical test of control response of a step as input. The proposed control was implemented on an intelligent sensor with a small microcontroller.
