Enhanced Control with a General Cascade Control Structure
Industrial & Engineering Chemistry Research, 2002In this paper, a general cascade control structure is proposed to handle stable, integrating, and unstable processes for cascade control systems. With the structure, a IMC controller is derived to get a desired closed-loop response and converted to a conventional PID controller.

Analysis of a Cascaded MPC Structure for Vehicle Motion Control
2021 American Control Conference (ACC), 2021Intelligent motion planning and control of automated vehicles and transportation systems have great advantages for increasing safety, energy consumption as well as driving comfort. Hereby, advanced control techniques and algorithms have to be developed meeting the challenging demands for passenger transportation.

A cascade structure for robust control design
IEEE Transactions on Automatic Control, 1994In the context of robust control theory and applications, the well-known variable structure approach and the so-called binary control approach offer both interesting properties and disadvantages. In this paper, the idea of combining the two techniques in order to define a cascade structure exploiting the desirable features of both approaches is ...

Improved Cascade Control Structure and Controller Design
Proceedings of the 44th IEEE Conference on Decision and Control, 2006In conventional single feedback control, the corrective action for disturbances does not begin until the controlled variable deviates from the set point. In this case, a cascade control strategy can be used to improve the performance of a control system particularly in the presence of disturbances.

Improved Cascade Control Structure for Controlling Unstable and Integrating Processes
Proceedings of the 44th IEEE Conference on Decision and Control, 2006Cascade control is an alternative to conventional single feedback control to improve the performance of a control system particularly in the presence of disturbances. However, so far published papers on cascade control strategies are for control of stable processes.

Advanced Control Structures in Multivariable Cascade
IFAC Proceedings Volumes, 1998Abstract The issues related to the use of cascade structures in multivariable controllers are addressed in this paper. An advanced structure, which makes use of a control scheme belonging to the IMC family is proposed. This control structure, which extends to the multivariable case the one of Semino and Brambilla (1996), is applied to a distillation ...

A cascade structure approach to control reconfiguration
2013 Conference on Control and Fault-Tolerant Systems (SysTol), 2013Fault tolerant control (FTC) seeks to avoid the deterioration of the system at the time that there is a change of one or more parameters outside the limits of tolerance. There is in the literature a set of approaches based on the idea of tracking the nominal trajectory, which have been proved to be effective.

An Efficient Structure for Parallel Cascade Control
Industrial & Engineering Chemistry Research, 1996A control structure capable of avoiding interactions between the two loops of a parallel cascade system is developed. A conventional controller is used in the inner loop and an IMC controller is inserted in the outer loop in order to reject only the effects of the perturbations that are not taken care of by the inner controller.

Analysis of cascade structure with predictive control and feedback linearisation
IEE Proceedings - Control Theory and Applications, 2005Predictive control and feedback linearisation are two popular approaches for the control of nonlinear systems. In this paper, a cascade combination of the two methods is proposed, where control based on input-output feedback linearisation forms the inner loop, and predictive control the outer loop. With this scheme, predictive control is applied to the
