Abstract�� Disturbance rejection control problem of turbo-shaft engine speed was studied. A disturbance rejection control scheme of turbo-shaft engine was proposed based on increment cascade adaptive disturbance rejection control (ICADRC). For one thing, cascade control structure was used to ensure that the disturbance in the inner loop can be suppressed in time. In this control structure, gas turbine speed was controlled in the inner loop, while power turbine speed in the outer loop. For another, in both control loops the control object was compensated from disturbance in virtue of extended state observation. Finally, digital simulation of integrated helicopter/engine system shows that the new control scheme can improve the power following character of turbo-shaft engine evidently, and can enhance the handling limit of integrated helicopter/engine closed loop system.
