N4SID-based output shaping control systems

An improved control strategy is presented for shaping control of stochastic distribution systems based on numerical subspace state space system identification (N4SID) method. The proposed controller aims at driving the output shape to follow the target shape, consequently, the product quality can be guaranteed while material consumption can be reduced in industrial processes. Additionally, the energy constraint on the control input is considered. Simulation results of a molecular weight distribution (MWD) control system validate the effectiveness and feasibility of the proposed control algorithm.
