In recent years significant progress has been made in the analysis and design of discrete-data and digital control systems. These systems have gained popularity and importance in industry due in part to the advances made in digital computers for controls and, more recently, in microprocessors and digital signal processors/5. Approved for public release; distribution is unlimitedThis paper presents the results of efforts to implement a hybrid control system at the U. S. Naval Postgraduate School, The salient features of this effort are use of real time digital computer programming, digital determination of instantaneous state variables, and, using the foregoing features to demonstrate optimum control of a second order : Lawrence E. McCullough and Gordon C. Jr. Nash. Hybrid Control Systems: An Introductory Discussion to the Special Issue Abstract— This introductory paper provides an overview of hybrid systems and gives a brief introduction to the major ap-proaches in hybrid systems research with several book references.

In digital control systems, the controller operation is implemented digitally. In the majority of control applications, however, the plant is an analog system. Digital control then results in hybrid systems, i.e., systems having both continuous-time and discrete-time parts. Such sys-tems are also referred to as sampled data systems (SDS). • A digital computer may serve as a compensator or controller in a feedback control system. Since the computer receives data only at specific intervals, it is necessary to develop a method for describing and analyzing the performance of computer control systems. • The computer system uses data sampled at prescribed intervals. second order system 22 6. a) speed torque characteristics of two phase ac servomotor. 28 b) speed torque characteristics of dc servomotor 32 7. step response of second order system 36 8. dc position control system 46 9. p,pi,pd and pid controller 52 root locus, bode & nyquist plot using mat lab 60 11 relationship between frequency responseFile Size: 1MB.

Physical processes modeled as hybrid systems In the technological and net-worked systems mentioned above, the digital and logic (embedded control) aspects are typically brought in by design in order to control the physics and mechanics of the system.
