A Novel Two-degree-of-freedom Control Strategy for Unstable Processes with Delay
نویسندگان
چکیده
A simple and practical two-degree-of-freedom control strategy is proposed for unstable processes with time delay. It can decouple load disturbance from setpoint response. By combining the theory on stabilizing PID controller proposed by Silva et al. with IMC method, the process in which the ratio of time delay to unstable time constant is smaller than 2 can be controlled effectively. Simulation examples are given to show the performance of the proposed method. Copyright © 2005 IFAC

Two-degree-of-freedom Control Scheme for Processes with Large Time Delay
In this paper, an analytical two-degree-of-freedom-control scheme is proposed for controlling processes with large time delay. The main contributions of this paper are that a setpoint response controller and an H∞ PID load-loop controller are developed based on optimal control theory, and control parameters are derived analytically. This structure can also be used to control integrating or unst...
متن کاملIdentification and Control of MIMO Systems with State Time Delay (Short Communication)
Time-delay identification is one of the most important parameters in designing controllers. In the cases where the number of inputs and outputs in a system are more than one, this identification is of great concern. In this paper, a novel autocorrelation-based scheme for the state variable time-delay identification for multi-input multi-output (MIMO) system has been presented. This method is ba...
متن کاملA Two-degree-of-freedom Smith Control for Improved Disturbance Rejection
A two-degree-of-freedom Smith control scheme is proposed for improved disturbance rejection for stable delay processes. The resulting set-point and disturbance responses can be tuned by two controllers separately. A novel disturbance controller design is presented with easy tuning and greatly improved performance. The internal and robust stability issues are discussed. Examples are provided for...
متن کاملDelay Dependent H∞ Based Robust Control Strategy for Unified Power Quality Conditioner in a Microgrid
This paper proposes a novel robust control scheme based on delay-dependent H∞for unified power quality conditioner (UPQC) in a microgrid under the influence of the delay and parameter uncertainties. A new UPQC model considering the effects of the delay and parameter uncertainties is established. Then, the H∞ controller is designed based on the cone complementarity linearization (CCL) algorithm....
متن کاملA 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...
