给出并证明了非光滑非线性多时滞Volterra积分系统最优控制和光滑非线性多时滞Volterra积分系统near-optimal控制的必要条件与充分条件.
The author studies the optimal and near-optimal controls of the Volterra integral system with time lags. Necessary and sufficient conditions of optimal controls for the nonsmooth nonlinear system and the ones of near-optimal controls for the smooth nonlinear system are derived successively.
