PID - Control Design for Power Station Processes Based on Time-Delay Compensation - Smith Predictor

چکیده
Abstract: This paper presents a new method for a PID-control design in which the PID-control loop is represented as an equivalent one to a control loop operating with an optimized PI-controller and a Smith predictor. It requires the nearest approximation of the power plant process description and the dead-time transfer function. The presented method is based on the PID-controller transfer function identification, which approximately describes dynamical properties of the optimal PI-controller with the Smith predictor. The tuning of PID controllers implemented on power plant processes of the Israel Electric Corporation (IEC) provides sufficiently good settings of these controller parameters and exemplifies industrial application of this approach.

A Unified IMC based PI/PID Controller Tuning Approach for Time Delay Processes
This paper proposes a new PI/PID controller tuning method within filtered Smith predictor (FSP) configuration in order to deal with various types of time delay processes including stable, unstable and integrating delay dominant and slow dynamic processes. The proposed PI/PID controller is designed based on the IMC principle and is tuned using a new constraint and without requiring any approxima...
متن کاملPID-Fuzzy Control Method with Time Delay Compensation for Hybrid Active Power Filter with Injection Circuit
Due to inherent time delays in the control system of Hybrid Active Power Filter with Injection Circuit (IHAPF) and the load harmonic currents changes rapidly and dramatically. In order to eliminate these harmonic currents, an IHAPF to be used must be able to respond quickly following variable of the harmonic currents. So, this paper proposes a PID-fuzzy control method with time-delay compensati...

In this paper a new method is introduced and investigated for removing the destabilizing effects of time-delay parameter in control loops. The concept of the method is taken from the knowledge concerning the dynamic behaviour of irrational transfer functions (Ir-TF), which is discussed and investigated elswhere in frequency response domain and is explained briefly here. Ir-TFs, which are we...
متن کاملTime Delay and Data Dropout Compensation in Networked Control Systems Using Extended Kalman Filter
In networked control systems, time delay and data dropout can degrade the performance of the control system and even destabilize the system. In the present paper, the Extended Kalman filter is employed to compensate the effects of time delay and data dropout in feedforward and feedback paths of networked control systems. In the proposed method, the extended Kalman filter is used as an observer ...
متن کاملNeural-Smith Predictor Method for Improvement of Networked Control Systems
Networked control systems (NCSs) are distributed control systems in which the nodes, including controllers, sensors, actuators, and plants are connected by a digital communication network such as the Internet. One of the most critical challenges in networked control systems is the stochastic time delay of arriving data packets in the communication network among the nodes. Using the Smith predic...
