Application and Evaluation of an LPV Integral Sliding Mode Fault Tolerant Control Scheme on the RECONFIGURE Benchmark

This paper describes the application of a linear parameter-varying integral sliding mode control allocation scheme to the RECONFIGURE benchmark model to deal with an elevator failure/fault scenario. The proposed scheme has the capability to maintain the closed-loop nominal load factor control performance in the face of elevator failures/faults, by effectively redistributing a retro-fitted signal to the healthy elevators without reconfiguring the baseline controller. In order to reduce any chattering appearing in the elevator demands, the retro-fitted signal is based on a super-twisting sliding mode structure. The efficiency of the scheme is evaluated using an industrial functional engineering simulator (FES) as part of the RECONFIGURE project.
