Stability of Siso Systems with Averaged Controllers

Controller Design for Integrating Processes in Siso or Mimo Systems

A two-step design t o control integrator processes in an SISO or MIMO system is proposed. For an SISO system, the first step of the design is to stabilize the integrator process with P&D modes in a secondary loop to achieve good stability robustness and modest performance. In the second step of design, a P&I controller in the primary loop is derived to improve the overall performance. By this w...

Global Stabilization of Attitude Dynamics: SDRE-based Control Laws

The State-Dependant Riccati Equation method has been frequently used to design suboptimal controllers applied to nonlinear dynamic systems. Different methods for local stability analysis of SDRE controlled systems of order greater than two such as the attitude dynamics of a general rigid body have been extended in literature; however, it is still difficult to show global stability properties of...

Passivity-Based Stability Analysis and Robust Practical Stabilization of Nonlinear Affine Systems with Non-vanishing Perturbations

This paper presents some analyses about the robust practical stability of a class of nonlinear affine systems in the presence of non-vanishing perturbations based on the passivity concept. The given analyses confirm the robust passivity property of the perturbed nonlinear systems in a certain region. Moreover, robust control laws are designed to guarantee the practical stability of the perturbe...

Robust Controller Design Using Edge Theorem for Modular Servo System

The paper deals with the design of robust controllers for uncertain SISO systems in the frequency domain. The approach is accomplished with the Edge Theorem and the Neymark D-partition method for the affine model. The proposed method guarantees the required degree of stability. The practical application is illustrated by the robust controller design for a Modular Servo System.
