The acceptance of tele-robotics and teleoperations through networked control system (NCS) is increasing day-by-day. NCS involves the feedback loop wherein components such as actuators sensors are controlled allowed to share their over real time network with distributed users spread geographically. performance surgical complications majorly depend upon delay, packet dropout jitter induced in sys...

The stability and accuracy of power hardware-in-the-loop (PHIL) setups are sensitive to deteriorated by the dynamics non-ideal characteristics their interfaces, such as time delay, noise perturbation, signal distortion. In this paper, a compensation scheme comprising Smith predictor compensator is proposed mitigate impact delay on PHIL stability. Furthermore, an online system impedance identifi...

In technical practice often occur higher order processes when a design of an optimal controller leads to complicated control algorithms. One of possibilities of control of such processes is their approximation by lower-order model with time-delay (dead time). One of the possible approaches to control of dead-time processes is application of predictive control methods. The paper deals with desig...

igestion is a hot topic in pulp production at Skeena Cellulose in Prince Rupert, British Columbia, Canada. A new continuous digester control system uses a new predictive adaptive process controller to provide closed-loop control of Effective Alkali and reduced Kappa Number variability. The installation of this controller has resulted in production cost savings of $0.60 per ton of pulp and proje...

Time-delay often appears in many control systems (such as aircraft, chemical or process control systems) either in the state, the control input, or the measurements. Unlike ordinary differential equations, delay systems are infinite dimensional in nature and time-delay is, in many cases, a source of instability. The stability issue and the performance of control systems with delay are, therefor...

The flow coupled liquid level control systems are extensively used e. g. in chemical processes and refineries in the petrochemical industry. These processes are characterized by high-order dynamic behaviour or large time constants and time-delays. Time-delays (dead time) are mainly caused by the duration needed to transport mass, energy or information. In many cases time-delay is caused by the ...
