12. [8 pts] Consider the following block diagram of a closed-loop system. Ysp U Ke2 Kel 2 (58+1)(8+1) 8- 10 7 6 (a) [2 pts] Calculate the range of Ke values which can make the inner-loop stable. (b) [3 pts] Assuming that Ke1 = 10, calculate the closed-loop transfer functions from P to U and D to U. Based on the result, draw an equivalent block diagram without the inner-loop. (c) [3 pts] Using the block diagram obtained in (b), calculate the range of K2 values which can make the overall closed-loop system stable. Y
