A strategy of two degrees of freedom(2-DOF) control combined with the method of reference model feedforward,which was applied to study on the design of command tracking controller for missile s longitudinal control system,was presented based on linear matrix inequality(LMI) convex optimization approach.

Experiments show that the proposed system has high accuracy in finger tracking and fingertip detection.

Particle swarm optimization approach to index tracking problem with a cardinality constraint

In this paper,by inducing into the active management strategy in the asset allocation of index fund,the Stein rule index tracking model is put forward to improve the tracking precision of index fund.

By considering the constraints of no short selling and the realistic condition of the adjustment of target index,the directly tracking performance of the cointegration optimization index tracking approach based on the time series of securities prices for the targeting index is researched in this paper.
