In this paper, control of stable, unstable and integrating processes with large time delay in
the presence of uncertainty, external disturbances and measurement noise is investigated …

This paper analyses the optimal nominal tuning of a new modification of predictive
disturbance observer (PDO) based filtered PI control (PDO FPI) applied to a first order plus …

Many researchers have achieved satisfactory control of unstable processes using complex
control structure involving two or more PI/PID controllers. However, a simple architecture is …

In this work, a recently reported two degree of freedom control structure namely the Parallel
Control Structure (PCS) is modified to achieve improved control performance for unstable …

This paper deals with the stability problem of linear delayed systems containing two
unstable real poles by means of PD controllers. The analysis presented is based on …

In this work, a novel optimized robust control algorithm, based on the mirror-mapping
method, is proposed for a class of industrial unstable process with time delay. The …

Parallel cascade control strategies, to improve the dynamic performance of a control system,
have been proposed earlier mainly for control of stable processes. In this paper, further …

Robustness analysis and design for the integrating unstable delay systems are discussed in
this note. The Nyquist criteria have established the exact stability margin of the novel robust …

This paper presents a neutral system approach to the design of an H∞ controller for input
delay systems in presence of uncertain time-invariant delay. It is shown that when …

In this paper, a new method to manage the stabilization and control problems of n-
dimensional linear systems plus dead time, which includes one, two, or three unstable …
