Course content
1. Regulated system - the concept of feedback control; control circuit diagram; video demonstrations of automatic control; study literature; conditions for completing the course. 2. Description of dynamic system - internal, external; differential equation; video transmission; transient and impulse functions, characteristics; static characteristic and its linearization; solution by Laplace transform and in Matlab. 3. Simulation of dynamic behavior of systems in Matlab-Simulink environment, method of reducing the order of derivation, method of gradual integration; influence and recalculation of initial conditions. 4. Division of regulated systems - static and astatic systems, systems with traffic delay; systems with minimal and non-minimal phase; real examples of systems; demonstrations in Matlab. 5.-6. Obtaining a description of the system - mathematical-physical analysis; example of a description of a real system; simulation in Matlab; experimental identification; approximation methods; optimization methods; model order reduction. 7.8. Frequency description of the system - frequency transmission; frequency response in the complex plane; frequency characteristics in logarithmic coordinates. 9. System stability - the effect of roots on stability; a necessary condition of stability; algebraic and frequency stability criteria; criterion Hurwitz, Routh-Shur; Mikhailov's criterion; simplified Nyquist criterion. 10. Branched circuits - solution by signal equations; signal diagrams; block algebra; Mason's formula. 11. Two-position - courses of working oscillations for power inputs and loads of various types; possible ways to improve the control process by means of a three-position controller; demonstrations in Matlab. 12.-13. PID controller - parallel and serial representation; characteristics; influence of adjustable on regulation; experimental adjustment; stability area; optimal adjustment; Ziegler-Nichols, Cohen-Coon, Chien-Hrones-Reswick adjustment; assessment of the quality of the regulatory process; examples of adjustments in Matlab. 14. Means of automatic control - industrial PID controllers; sensors, actuators; measuring cards; software means for automatic control; LabVIEW; discrete shapes of the PID controller.
