This paper presents a solution to two disk mixed sensitivity problems on the basis of pole assignment. The sensitivity function and the complementary one are decomposed to the product of two functions respectively. One of them is chosen to satisfy the sensitivity specification or the robust stability one. If the gain of the other function are less than one, the problem is solved. It is shown that the decomposition and the gain adjustment can be easily accomplished by two parameters on a graphics. The procedure and numerical examples are presented. We get lower sensitivity solution than H_∞ control approach to one disk problem.
