摘要

This article presents the details of designing a linear parameter-varying (LPV) controller for a tensegrity-membrane system. The major control objective is to deploy the system from its initial packaged configuration to its final deployed configuration. Since LPV synthesis naturally leads to an infinite-dimensional linear matrix inequality (LMI) problem, a grid-ding method is used to reduce it to a finite-dimensional LMI problem and the control design is performed using a control-oriented model based on the linearized system dynam-ics at a set of system equilibriums. To test the performance of the resulting controller, a nonlinear finite element model and the control-oriented model are used in numerical sim-ulations. To test the robustness of the controller, sensor noise is considered in another non-linear finite element simulation and the results are compared with the simulation results given by the nominal system.
