We propose a distributed model predictive control approach for linear time-invariant systems coupled via dynamics. The proposed approach uses the tube MPC concept for robustness to handle the disturbances induced by mutual interactions between subsystems; however, the main novelty here is to replace the conventional linear disturbance rejection controller with a second MPC controller, as is don...

The objective of this paper is to design a real-time control solution for chemical processes, namely the ethylene reactor, the key-installation in the petrochemical industry. The controller used is lag or lead controller, a simple yet suitable control tool. This article deals with the problem of finding all first order controllers that stabilize a given LTI continuous time or discrete time plan...

A 38-year-old tuberculous male Pakistani presented with halitosis and a cough especially marked when lying on his left side. Barium swallow demonstrated a fistula between oesophagus and left main bronchus. Anti-tuberculous therapy and repeated cauterization failed to close the fistula. Thoracotomy confirmed a congenital oesophago-bronchial fistula. Division and suture resulted in cure.

We report on a 65-year-old female who complained of recurrent bronchopulmonary infections since 1999. She suffered from permanent cough and progressive dyspnea. The diagnosis of amyloidosis was made by bronchoscopic tissue biopsies, during which severe bleeding occurred. Argon-plasma-laser treatment stopped the bleeding and resulted in a successful recanalization of the left main bronchus. The ...

—The article deals with the cascade nonlinear control of a chemical continuous stirred tank reactor. The control is performed in primary and secondary control-loops where the primary controlled output of the reactor is a concentration of the main reaction product and the secondary output is the reactant temperature. A common control input is the coolant flow rate. The controller in the primary ...

In this paper a PI based adaptive control system is developed to control an organic Rankine cycle power plant. In particular, the control of the turbine speed during the transient between the normal operation mode of the system (connected to the grid) and the islandmode (connected to a stand-alone load) is of main concern. A control algorithm suitable for the implementation on a programmable lo...

In this paper, the robot with three wheels is implement and its motion is controlled . two of robot’s wheels are activated by DC motors. The main PID controllers are implemented with a Field Programmable Gate Array(FPGA) for independent robot movement . a FPGA controller communicate with a PC with PCI card(PLX9052) so that the movement of wheels can be displayed on the monitor through PCI card ...

In this paper, we consider the controller synthesis problem for a class of uncertain hybrid dynamical systems. The goal is for the closed loop system to exhibit desired behavior under dynamic uncertainty and exteriors disturbances. The main question is whether there exists a controller such that the closed loop system satisfies the specification. The notion of attainability is introduced to ref...

The main concern about the bi-directional AC-DC converter is to maintain utility power factor near to unity. One Cycle Controller (OCC) is one of the outstanding control techniques to control these power electronic converters. One Cycle Controller comprises one integrator with reset along with a few linear components like analog comparators, flip-flops, and a clock. This paper presents a hardwa...

In this paper we aim at polynomial synthesis of a two-degree-of-freedom (2DoF) controller with integral action for a coupled tank system using the Polynomial Toolbox. The main advantage of the proposed 2DoF controller is in computational savings compared to classical feedback design. It will be shown that the procedure leads to solving of two spectral factorizations where the closed loop poles ...
