Title: Improvement of a Proportional-Integral (PI) Controller for a Servo Pneumatic Actuator by Adapting Zero-Compensator Placement Method
Abstract: Transient response characteristics are one of the critical aspects in designing a controller for a servo pneumatic system. Scholars have introduced numerous controllers for research enhancement and industry applications. One of the significant set-back observed for the industry application is that the controllers that have been proposed are complex and involves highly mathematical algorithms, thus requires high processing energy and time to support the system. Owing to this reason, a Proportional-Integrator (PI) controller with a "zero-compensator", using the zero-placement method, is implemented to overcome the complexity. The controller is simple, functional, and practical compared to other controllers. Based on the simulation, it is concluded that the implemented controller shows a significant improvement in the servo pneumatic systems response compared to a PI Controller. Rise time, TR improve by 66.22%, per cent overshoot, %OS by 96.49%, and settling time, TS by 89.12%. A complete set of transient response parameters were validated to add to the analysis. The research suggests the designed controller be tested experimentally to the fully equipped pneumatic system. An improved adaptive type of the same controller is also an area of interest. Previous research shows that an adaptive pole placement controller has successfully been applied to servo pneumatic systems.
