[more ▼] Plugging is well known to be a major cause of instability in industrial cement mills. A simple nonlinear model able to simulate the plugging phenomenon is presented. It is shown how a nonlinear robust controller can be designed in order to fully prevent the mill from plugging [less ▲] Detailed reference viewed: 9 (1 ULg) Use of plant peptone-containing serum-free media for the cultivation of CHO cells in suspension and on microcarriers; ; et al in Animal Cell Technology : from target to market (2001) Detailed reference viewed: 8 (1 ULg)Global stabilization of feedforward systems with exponentially unstable Jacobian linearization; Sepulchre, Rodolphe ; in Systems & Control Letters (1999), 37(2), 107-115 The global stabilization of a class of feedforward systems having an exponentially unstable Jacobian linearization is achieved by a high gain feedback saturated at a low level.

[more ▼] The global stabilization of a class of feedforward systems having an exponentially unstable Jacobian linearization is achieved by a high gain feedback saturated at a low level. The control law forces the derivatives of the state variables to small values along the closed loop trajectories. This “slow control” design is illustrated with a benchmark example and its limitations are emphasized. [less ▲] Detailed reference viewed: 12 (1 ULg) |
