A Design Method for Robust Stabilizing Modified Pid Controllers for Time-delay Plants with Uncertainty

چکیده
We examine a design method for robust stabilizing modified proportional– integral–derivative (PID) controllers for time-delay plants with uncertainty. The PID controller structure is very widely used in industrial applications. However, the plants to which the PID controller is applicable are restricted. Yamada, Hagiwara and Shimizu proposed a design method for robust stabilizing modified PID controllers for any plant with uncertainty. However, no method has been published to guarantee the robust stability of a PID control system for any time-delay plant with uncertainty. In this paper, we propose a design method for robust stabilizing modified PID controllers for any time-delay plant with uncertainty.

A Design Method for Robust Stabilizing Simple Repetitive Controllers for Time-delay Plants
A simple repetitive controller was proposed by Yamada et al. It works as a modified repetitive controller. The transfer functions from the periodic reference input to the output, and from the disturbance to the output have a finite number of poles, and the input–output characteristics and the disturbance attenuation characteristics can be specified easily. However, this method cannot be applied...

In the process control industry, majority of control loops are based on ProportionalIntegral-Derivative (PID) controllers. The basic structure of the PID controllers makes it easy to regulate the process output. Design methods leading to an optimal and effective operation of the PID controllers are economically vital for process industries. Robust control has been a recent addition to the field...

متن کاملModelling and Compensation of uncertain time-delays in networked control systems with plant uncertainty using an Improved RMPC Method
Control systems with digital communication between sensors, controllers and actuators are called as Networked Control Systems (NCSs). In general, NCSs encounter with some problems such as packet dropouts and network induced delays. When plant uncertainty is added to the aforementioned problems, the design of the robust controller that is able to guarantee the stability, becomes more complex. In...
