This paper presents a new approach to the simultaneous optimum design of a structural and control system in order to realize an increasing number of elements. For simplicity, we take up a flexible beam as a dynamic model which based on the Euler-Bernoulli theory. The lateral vibration of beam is controlled under given disturbance. For simplicity, the transformation ratio of cross-sectional area is taken as a structural design variable. In this way, the number of the structural design variable is only one in spite of the increasing number of elements. However, the shape of the structure is limited. The location of the sensor and actuator is taken as a control design variable. These two design variables are optimized to minimize a performance function composed of kinetic and control energy. In the numerical examples, it is shown that the simultaneous optimum design of the structural and control system is useful.
