AN OPTIMAL VARIABLE STRUCTURE STABILIZER FOR A MULTIMACHINE GENERATING PLANT
… plant are proposed. The first one, named the Optimal Multivariable Stabilizer (OMS), is based on linear optimal control theory and the Generalized Heffron-Phillips model of a multimachine plant. The second design, named the Optimal Variable Structure Stabilizer (OVSS), is based on a …

Application of control theory to large flexible structures using the Independent Modal-Space Control method
The control problem of a large-order flexible system in the form of a beam-lattice is presented using the Independent Modal-Space Control (IMSC) method. The method is based on a transformation of the system equations of motion to modal space, yielding internally independent modal equations of …

Integration of Life Sciences and Engineering - Highly Infectious Diseases in Population : Control System Analysis and Synthesis
… a certain metropolitan population. The chosen nonlinear model is simulated using MATLAB and Simulink to obtain input-output relations in the time domain. Next, the nonlinear model is linearized around an equilibrium point to demonstrate the analysis of the linear system exhibiting control system …

A perturbation approach to control of rotational/translational maneuvers of flexible space vehicles
An open loop control law is applied to a flexible spacecraft that admits translational, as well as rotational and flexural motion. The translational degrees of freedom are coupled to the rotation and deformation through the active controls applied to the structure. The objective of any maneuver is …

The coordinated control of space robot teams for the on-orbit construction of large flexible space structures
… in earth orbit. This work focuses on the control of teams of robots performing construction tasks such as manipulation and assembly of large space structures. The control of the robot structure system is difficult. The space structures are flexible and there are significant dynamic …

General Vector Explicit - Impact Time and Angle Control Guidance
… General Vector Explicit - Impact Time and Angle Control Guidance (GENEX-ITACG). The motivation for GENEX-ITACG came from an explicit trajectory shaping guidance law called General Vector Explicit Guidance (GENEX). GENEX simultaneously achieves design specifications on miss distance and terminal …

Active control of distributed structures
… differential equations of motion for an uncontrolled distributed structure can be transformed into a set of independent modal equations by means of the system eigenfunctions. In vibration analysis, the modal coordinates are referred to as natural coordinates. Active control forces generally …

Validated global multiobjective optimization of trajectories in nonlinear dynamical systems
… optimization of trajectories in continuous nonlinear dynamical systems that can provide rigorous, arbitrarily tight bounds on the objective values and state paths realized by (Pareto-)optimal trajectories. By controlling all sources of error, our resulting method is the first global trajectory …
