Abstract :
This paper presents a new strategy to robust fault
tolerant control (FTC) to optimise the wind energy captured by
a wind turbine operating at low wind speeds, using an adaptive
gain Sliding Mode Control (SMC). In addition to the inherent
robustness of SMC against matched model uncertainty, the
proposed method involves a robust descriptor observer design
that can provide robust simultaneous estimation of states and
the “unknown outputs” (sensor faults and noise) in order to
guarantee the robustness of the sliding surface against
unknown output effects. Moreover, the sliding surface is
designed to achieve the required objectives by utilizing the
nonlinear flexible two mass model of the variable speed wind
turbine. The proposed FTC SMC method is applied to a 5 MW
wind turbine benchmark model
