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.
