Feedback control system to control the composition of the output stream in a stirred tank blending process is shown in Figure 11.1 page 176 of Textbook (as shown below). Figure Il Composition control system for stirred-tank blending process Mass train of the output stream is the controlled variable flow ratew of the input stream the manipulated variable and mattraction 1 of the other input stream is the disturbance variable.
