Thoroughly classroom-tested and proven to be a valuable self-study companion, Linear Control System Analysis and Design: Sixth Edition provides an intensive overview of modern control theory and conventional control system design using in-depth explanations, diagrams, calculations, and tables. Keeping mathematics to a minimum, the book is designed with the undergraduate in mind, first building a foundation, then bridging the gap between control theory and its real-world application. Computer-aided design accuracy checks (CADAC) are used throughout the text to enhance computer literacy. Each CADAC uses fundamental concepts to ensure the viability of a computer solution. Completely updated and packed with student-friendly features, the sixth edition presents a range of updated examples using MATLAB®, as well as an appendix listing MATLAB functions for optimizing control system analysis and design. Over 75 percent of the problems presented in the previous edition have been revised or replaced.

The controller must be implemented using a particular control processor This speci cation limits the complexity of the controller 1.2.4 The Controller Design Problem Once the system to be controlled has been designed and modeled, and the designer has identi ed a set of design goals (consisting of performance goals, robustness requirements, and control law constraints), we can pose the controller design. .. state-space methods of linear controller design include Franklin, Powell, and Emami FPE86] and Chen Che87] Linear quadratic methods for LTI controller design are covered in Athans and Falb AF66, ch.9], Kwakernaak and Sivan KS72], Anderson and Moore AM90], and Bryson and Ho BH75] Three recent books on LTI controller design deserve special mention: Lunze's Robust Multivariable Feedback Design Lun89], Maciejowski's... subsystems Simulation Complex models can be rapidly simulated Controller design Enormous computing power is now available for the design of controllers This last observation is of fundamental importance for this book 1.3.2 Challenges for Controller Design The technology advances described above present a number of challenges for controller design: More sensors and actuators For only a modest cost, it... designer using a classical controller design scheme is only likely to nd a controller that meets a set of speci cations that is achievable and, of course, certain not to nd a controller that meets a set of speci cations that is not achievable Many controller design techniques do not have any way to determine unambiguously that a set of speci cations is not achievable For controller design problems of the...
