Decoupling control based on support machines ath-order inversion for the boiler-turbine coordinate systems

A boiler-turbine unit is a typical multi-input multi-output (MIMO) industrial control system in power plant, which has nonlinear and couple characteristics. As there exist strong couplings between main steam pressure and power output, we present a new coordinated control strategy: ath-order inverse system method based on Support Vector Machine (SVM). Cascading SVM inversion with the original system can form a pseudo-linear system. Then we can solve the problem of nonlinear system by the traditional linear system methods. Simulations show that this strategy has good control performance and can be implanted for engineering.
