Dec. 17,2019 ENGR 447-02 Control Systems (Fall 2019) 10. Mention one method of experimentally estimating a system transfer function. 11. The differential equation of a nonlinear system is given by: Page 2 of 5 -1; + - What is the B matrix of the linearized system at operating point ₁₂ == 1.0? (Note: not asking for A, just find B matrix.) 12. What are: a. characteristic polynomial, b. characteristic equation and c. poles of below state space system. Is the system stable? Explain -+y=11] 13. System of Question 12 above is converted into a discrete time system using "zero order hold" method (sample time T = 0.1). What are the discrete time system Ca and Da matrices? 14. Find the poles of below discrete time state space system. Is the system stable? Explain. **+1=6x+y=13_0]xx -1.1 A continuous time state space system has two poles: s₁ =-2, s₂ =-1. What are the poles of its discre time system when conversion method is zero order hold with sampling period of T=0.1 seconds?
