Programma

Basic Control Tools

Bounded- input bounded- output linear systems. Pole placement theorem for controllable and observable linear systems. Luenberger observers for observable systems. Design of dynamic compensators for linear systems. Integral feedback control to reject constant disturbances. PID control. System inverses for minimum phase linear systems. The combination of feedback and feedforward control actions.

Advanced Control Tools

Linear approximations of nonlinear control systems about operating conditions. The definition of region of attraction for an operating condition. Output feedback compensators with integral actions to control a nonlinear systems about a given operating condition. Liapunov matrix equations to determine quadratic Liapunov functions and assess the region of attraction. The definition of sensitivity transfer function and its properties. The gang of four: sensitivity, complementary sensitivity, load sensitivity and noise sensitivity funtions. How to determine the robustness of a control loop using the gang of four functions. Bode’s integral formula and the limitations imposed by unstable open loop poles. Youla parametrization to design stable compensatiors. Kalman filters, Riccati equations and robust control design.

Control Design for Multivariable Nonlinear System

Relative degree for a single input single output nonlinear system. State feedback control design for input-output linearization. State feedback linearization when the relative degree is equal to the state space dimension. The definition of nonlinear inverse systems. Relative degrees or decoupling indices for multivariable (multi-input, multi-output) nonlinear systems. The definition of the decoupling matrix. State feedback control design for input-output linearization when the decoupling matrix is full rank using the Penrose pseudoinverse. State feedback linearization when the sum of relative degrees is equal to the state space dimension and the decoupling matrix is full rank.

Statistiche

Questa sezione riassume le statistiche relative alle votazioni di profitto ottenute dagli studenti dall'anno accademico 2010-11 ad oggi. I dati sono aggiornati frequentemente, ma non in tempo reale. Essi si riferiscono comunque soltanto agli esami sostenuti da studenti iscritti al Corso di Laurea o Laurea Magistrale in Ingegneria Elettronica.
Nel calcolo sono inclusi gli esami dello stesso corso con diverso codice.
Il 30 e lode è considerato come 31 nel calcolo della media e dello scarto quadratico medio.
