H1 Fieldbus Network Delay; A Digital Pole Placement Control Design

چکیده
This paper presents a pole-placement based control algorithm to treat ISA Fieldbus H1 delay problems. A digital network delay model is embedded with the process model in order to design a suitable closed-loop controller. The effect of different values of network delay against sampling time is analyzed. Pole-placement technique should not simplify zeros in order to achieve stability in closed-loop. Simulation results show the efficiency of the proposed control algorithm. It also gives a preliminary study on the effect of network delay jitter on closed loop performance.

Design and Practical Implementation of a New Markov Model Predictive Controller for Variable Communication Packet Loss in Network Control Systems
The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...

متن کاملDecentralized Controller Design by Continuous Pole Placement for Commensurate-Time-Delay Systems
Decentralized controller design problem for linear time-invariant retarded commensurate-time-delay systems is considered. The continuous pole placement algorithm, which has recently been introduced for static state vector feedback controller design for retarded time-delay systems, is first extended to design dynamic output feedback controllers. This algorithm is then used in the proposed decent...
