Abstract:

To address the noise amplification problem caused by the differential operation in the discrete-time zeroing neural network solution model for time-varying quadratic programming, a robust discrete-time zeroing neural network solution model is proposed. Firstly, a state space model of the differential operation via a polynomial prediction filter is established. Secondly a robust differentiator is proposed by a Kalman filter robust to the observation noise. It is demonstrated that the impact of the noisy observations on the solution model can be minimized in the sense of maximum a posteriori probability when the proposed robust differentiator is employed to replace the differential operations in the solution model. Finally, the simulation experiments demonstrate that the proposed method gives superior performance compared to the existing discrete-time zeroing neural network solution models, especially in the presence of noisy observations.

Key words: time-varying quadratic programming (QP), zeroing neural network, polynomial prediction filter, robust differentiator
