The Design of Guaranteed-Cost Tracking Controller For 3 DOF Helicopter

The design of the guaranteed-cost tracking controller for helicopter was studied with the 3DOF helicopter system. By linearizing the physical models of each freedom, the 6th order state-space was implemented to describe the dynamics. The parameterized representation of the state-feedback guaranteed-cost tracking controller was provided in the terms of linear matrix inequality (LMI). Experimental results are employed to investigate the effect of the combination of the two approaches.
