Robust T-S Fuzzy Control of Electrostimulation for Paraplegic Patients considering Norm-Bounded Uncertainties

الملخص EN

This manuscript presents a Takagi–Sugeno fuzzy control for a mathematical model of the knee position of paraplegic patients using functional electrical stimulation (FES).

Each local model of the fuzzy system is represented considering norm-bounded uncertainties.

After obtaining the model of FES with norm-bounded uncertainties, the fuzzy control strategy is designed through the solution of linear matrix inequalities (LMIs) using the conditions available in the literature, which consider these norm-bounded uncertainties.

The strategy considers decay rate and constraints on the input signal.

The model is simulated in the Matlab environment using the numerical parameters measured by experimental tests from a paraplegic patient.
