Discussion on: 'Robust Control of a Plasma Wind Tunnel: An LPV Discrete-Time System Depending on Fast/Slowly Varying Parameters' By F. Amato and M. Mattei

摘要

Design of a controller for nonlinear systems to follow reference/command is an active research topic in the past decade. The paper by Amato and Mattei tries to develop a practical solution for a physical system- Plasma Wind Tunnel. The proposed controller con- Sists of a nonlinear feedforward controller and a Gained scheduled linear feedback controller designed Based on the global linearisation of the plant along The reference trajectories. By shifting the main control Effort required for tracking a specific reference to the Nonlinear feedforward controller, the paper develops A practical procedure to design local linear controllers (although it is complicated in numerical computation) and stability results have been established.
