Modern Control Systems | 12th Edition
The Nichols diagram for Gc(jio)G(jcS) of a closedloop system is shown in Figure P9.22.The frequency for each point on the graph is given in the following table: Point 1 8 to 1 2.0 2.6 3.4 4.2 5.2 6.0 7.0 8.0 Determine (a) the resonant frequency, (b) the bandwidth, (c) the phase margin, and (d) the gain margin. (e) Estimate the overshoot and settling time (with a 2% criterion) of the response to a step input.
1.0 Introduction to Operating Systems. An operating system is a program that manages a computer’s hardware. It also provides a basis for application programs and acts as an intermediary between the computer user and the computer hardware. An amazing aspect of operating systems is how they vary in accomplishing these tasks. Mainframe operating systems are designed primarily to optimize utilization of hardware. Personal computer (PC) operating systems support complex games, business applications, and everything in between. Operating systems for mobile computers provide an environment in which a user can easily interface with the computer to execute programs. Thus, some operating systems are designed to be convenient, others to be efficient, and others to be some combination of the two. Be
