文摘
- •
A novel nonlinear PI controller is designed and tested for nonlinear flow process.
- •
The proposed controller can be used standalone for effective stiction compensation.
- •
The controller was experimentally tested on a nonlinear laboratory scale flow process.
- •
The designed controller is found to be superior to conventional PI controller.
