Abstract—In this paper, a design of a modified Internal Model Control for an unstable plant with an integrator in continuous-time system is proposed. The system becomes a stable system by stabilizing an unstable plant and it does not cause a steady-state error by an input side disturbance for an unstable plant with an integrator. We describe details of the proposed method including a design of stabilizing an unstable plant, a design of a disturbance compensator, and a design of whole system. In the simulation study, these simulation results are shown that the proposed method has a superior performance. The nominal plant and the plant with a modeling error can be stabilized and the proposed method can reduce influence by in an input side disturbance of an unstable plant.

Index Terms—Internal model control, unstable plant, disturbance compensator.
