The PID algorithm

The article proposes to use dual PID controller with optimized parameters adjusted through genetic algorithm (GA) to control the gantry crane. The first PID controller controls the load oscillations, while the second PID controller controls the position of the crane.

In this paper the authors find and optimize 3 constants in the algorithm of the PID controller. The controller can be used in the designs that have special requirements. The response of the controller can be described in terms of the sensitivity of the controller error. The error values are compared with setpoint value of the controller and the value of fluctuations of Quadcopters.

In this paper, we describe the application of CRO algorithm to search optimal parameters for PID controller because CRO combines both features of local and global searching techniques to increase the chance of finding global solution. The comparison of tuning PID controller by CRO and traditional Ziegler-Nichols method is also presented. The simulated results show the advantages of tuning PID using CRO compared to traditional methods in terms of performance indices and transient responses.

In this paper, a robust PI controller in combination with a linear quadratic regulator (LQR) is proposed to control a two-wheeled inverted pendulum robot (TWIPR) such that it is kept balanced while moving. The proposed TWIPR control system consists of two control loops. The inner loop has two PI controllers for two DC motors’ currents, which are separately designed based on a robust PI controller structure. The outer loop contains a LQR controller for the tilt angle, heading angle and position of the TWIPR.

This paper presents new results of PID neural network controller for heading control of ship. The control system uses one neural network to drive parameters of a PID controller. Another neural network is used to predict the ship’s heading so that it gives the predicted heading of k steps in advance.

In PID controller design, an optimization algorithm is commonly employed to search for the optimal controller parameters. The optimization algorithm is based on a specific performance criterion which is defined by an objective or cost function. To this end, different objective functions have been proposed in the literature to optimize the response of the controlled system. These functions include numerous weighted time and frequency domain variables.

The inner loop, a feedback control loop, is designed as a proportional – integral – derivative (PID) controller in order to eliminate unknown parts of the plants such as input-nonlinear elements, or unknown system disturbances. The outer loop, a learning feed-forward control (LFFC) loop, is designed based on the Model Reference Adaptive System algorithms called MRAS-based LFFC for compensating the cross-couple and non-linear elements.

Servo compensation usually implies that some type of filter network such as lead/lag circuits or proportional, integral, or differential (PID) algorithms will be used to stabilize the servo drive. However, there are other types of compensation that can be used external to the servo drive to compensate for other things in the servo plant (machine) that can, for example, be structural resonances or nonlinearities such as lost motion or stiction. These machine compensation techniques are shown in Figure 1 and are valid for either hydraulic or electric servo drives. 11.

Despite the great technological advancement experienced in recent years, Programmable Logic Controllers (PLC) are still used in many applications from the real world and still play a central role in infrastructure of industrial automation. PLC operate in the factory-floor level and are responsible typically for implementing logical control, regulatory control strategies, such as PID and fuzzy-based algorithms, and safety logics. Usually PLC are interconnected with the supervision level through communication network, such as Ethernet networks, in order to work in an integrated form....
