Abstract
- For a typical boiler-turbine model considering both external disturbances and parameter uncertainties, a new robust nonlinear adaptive backstepping coordinated control strategy is proposed. To conquer the effect of parameter uncertainties and avoid the possibly parameter-drift, the sufficiently smooth projection operators are used in the parameter updating laws. At the same time, the nonlinear-damping is added to the control laws to effectively inhibit the impact of external disturbance on the control quality. Finally, several simulation tests prove that the proposed coordinated control system not only can ensure asymptotical stability of the closed-loop system, but also has good effects in disturbance rejection, given value tracing and robustness.
