| 英文摘要 | Optimal tracking control (OTC) for discrete time-delay systems affected by persistent disturbance with quadratic performance indexes is considered. Optimal tracking controller is designed based on a sensitivity approximation approach. By introducing a sensitivity parameter, we transform the original OTC problem into a series of difference equations without time-advance on v terms. The obtained OTC law consists of analytic feedback and feedforward terms, and a compensating term, which is the sum of the infinite series of adjoint vectors. The compensation term can be obtained with an iterated formula for the adjoint vectors. A simulation example shows that the approximation approach is effective in tracking the reference input and robust with respect to exogenous persistent disturbances. |
