A new method is proposed to analyze a multirate feedback system by reducing it to an equivalent uniform- rate feedback system. The solution is essentially based on the developments of state-space model conversions in closed-loop systems with multiple rates. Either a slow-rate controlled system with a fast- rate feedback or a fast-rate controlled system with a slow-rate feedback is modeled by state-space expressions with either a unified slow-rate frame or a unified fast-rate frame. It is shown that the proposed method is suitable for computer programming and convenient for analysis and design of multirate sampled-data control systems.
