A Novel Modified Delay-Based Control Algorithm with an Experimental Application

Abstract

In the present article, a new modified delay-based control structure is proposed to improve the closed-loop performance of control systems. The controller is designed for a second-order linear time-invariant system. The controller parameters are tuned by using the integral of the absolute error criterion. Theoretical results are simulated and experimentally applied to an electromechanical system, which is identified with an interactive system identification tool. It is shown that the present controller provides better control measures and time domain specifications compared with the classical PID and PI-PD controllers in the presence of measurement noise as well as uncertainties.

Optimal Control of AVR System With Tree Seed Algorithm-Based PID Controller

“…In general, the method of IAE, ISE, ITSE, and ITEA are often used to evaluate PID controller design performance in the literature [11], [13], [36]- [38]. Instead of evaluating these error criterias as only objective, Zwe-Lee Gaing's study demonstrated that the aim of the combinations of these error criterias, which include weight factors, is a better way to form a common objective [11].…”

Model Predictive Control of UCG: An Experiment and Simulation Study

“…Nowadays, various methods of technological process control are being developed, e.g., [42,44]. The MPC controller is conceived as multidimensional, i.e., it works in a coordinated manner with a higher number of manipulated variables (MVs) and controlled variables, i.e., measured outputs (MOs) what is typical in MIMO or MISO systems.…”
