transfer function of 2/ 8. Figure 9.30 shows an electrical circuit and its block diagram representation. What is the overall transfer function of the system? 9. Use block simplification to arrive at the overall transfer function of the systems shown in Figure 9.31. 10. What is the overall transfer function for the systems shown in Figure 9.32? 11. A closed-loop negative feedback system to be used for controlling the position of a load has a differential amplifier with transfer function K₁ operating a motor with transfer function 1/(sL + R). The output of the motor operates a gear system with gear ratio N and this, in turn, operates a screw with transfer function 1 to give the resulting displacement. The position sensor is a potentiometer and this gives a feedback voltag related to the position of the load by the transfer function K₂. Derive the transfer function for the system a whole, relating the input voltage to the system to the displacement output. 12. A closed-loop negative feedback system for the control of the height of liquid in a tank by pumping liquid from a reservoir tank can be considered to be a system with a differential amplifier having a transfer funct of 5, its output operating a pump with a transfer function 5/(s + 1). The coupled system of tanks has a transfer function, relating height in the tank to the output from the pump, of 3/(s + 1)(s + 2). The feedback sensor of the height level in the tank has a transfer function of 0.1. Determine the overall transfer function the system, relating the input voltage signal to the system to the height of liquid in the tank. 13.
