Abstract—We consider a control problem of a chain of integrators where there is a finite constant delay in the input and uncertain AC and DC sensor noise in the feedback channel. If a finite constant delay and uncertain sensor noise are included in a controller via the feedback channel, the signal is distorted and the entire system cannot work normally. Therefore, some appropriate action for a finite constant delay and uncertain AC and DC sensor noise effect is essential in the controller design. Our control scheme is equipped with a gain-scaling factor, an amplifier, and a compensator to keep the system states bounded and reduce the ultimate bound of the output arbitrarily small. Our result shows that the proposed method has a distinct advantage over the existing results.
