Optimization based control strategy for second order unstable processes
with time delay
Abstract
In this paper, stabilization and control of linear time-invariant
systems with two unstable poles and time delay are looked at. It is well
known that time delays make it harder to analyze stability and come up
with good control strategies. Because of this, suggest a simple control
strategy based on “dynamic optimization” to stabilize this type of
system. In this work, dynamic optimization (DO) to figure out the PID
controller parameters for a process that is unstable in second order
plus time delay (SOPTD). In particular, the process model is used to
figure out the controller parameters so that integral performance
criteria and controller variations are kept to a minimum (such as ISE,
IAE and TV). The controller responses looked at both the set-point
following the load disturbance rejection. Robustness studies have been
carried out for uncertainties in the process parameters. Lastly, some
examples are given to demonstrate the controller performance and
robustness.
