Abstract :
We consider a networked control system that utilizes unreliable channels where packets may be lost. By modeling the losses as stochastic processes, we propose a mixed H2/H∞ control approach for synthesis of a controller that depends on the information regarding the losses. The approach is applied to a bilateral teleoperating system. Numerical results show that the proposed control achieves desired performance.
