摘      要：A multivariable inverse nonlinear control scheme is developed to decouple the strongly nonlinear double extraction steam turbo unit, improving the transient stability of the power and heating system. Computer simulation tests show that not only does the control scheme achieve satisfactory decoupling of the high and low pressure turbines and the electric power, remarkably improving the transient stability, but also the design is very intuitive and concise. 
