Invariance control for a class of cascade nonlinear systems

We consider the control of partially linear cascade systems using switching control of the states of the linear subsystem. We give suucient conditions under which feedback of the linear states with switching gains guarantees both exponential stability of the linear subsystem and positive invariance of a compact region in state space. Semi-global asymptotic stabilization follows under some addit...

Application of Cascade Nonlinear Control for a CSTR

—The article deals with the cascade nonlinear control of a chemical continuous stirred tank reactor. The control is performed in primary and secondary control-loops where the primary controlled output of the reactor is a concentration of the main reaction product and the secondary output is the reactant temperature. A common control input is the coolant flow rate. The controller in the primary ...

H∞ Control for a Class of Non-Minimum-Phase Cascade Switched Nonlinear Systems

This paper is concerned with the H∞ control problem for a class of non-minimum phase cascade switched nonlinear systems. The system under consideration is composed of two cascade-connected parts which are also switched systems. Sufficient conditions under which the H∞ control problem is solvable under an arbitrary switching law are presented. The Common Lyapunov function and the switched state ...

Modeling, Control and Simulation of Cascade Control Servo System for one Axis Gimbal Mechanism

The gimbal stabilization mechanism is used to provide the stability to an object mounted on the gimbal by isolating it from the base angular motion and vibration. The purpose of this paper is to present a model of control servo system for one axis gimbal mechanism using a cascade PID controller. The gimbal torque relationships are derived by taking into consideration the base angular motion. Th...
