Abstract
This paper presents the design of a servo-integrator type state-space digital control structure for an air pressurization plant. The plant is characterized by slow dynamics with output delay. To evaluate the performance of the servointegrator controller, two control structures, namely, STR-PID and conventional PID are tuned and implemented. With the results obtained, a comparative analysis is performed based on metrics related to time response and control effort. At the end, it is evidenced that the Servointegrator type state space controller outperformed the other two controllers, demonstrating that it is an effective strategy that allows controlling systems with slow dynamics and dead time in the output.
