Stabilization and Control
نویسنده
چکیده
Automized stabilization and control of computer-controlled nonlinear processes is considered. A new algorithm which constitutes a combination of Popov's and of Jury and Lee's stability criteria with a nonlinear programming approach is proposed. The algorithm is applied to a digitally controlled antenna tracking system and the operation is simulated on an IBM 360/91 computer. The solution involves a novel application of nonlinear programming algorithms to problems with complex variables. A comparative study of various unconstrained minimization methods used by the proposed algorithm was performed. Index Terms -Computer process control, nonlinear programming, nonlinear systems stability, real-time systems, unconstrained minimization techniques.

Robust stabilization of a class of three-dimensional uncertain fractional-order non-autonomous systems
This paper concerns the problem of robust stabilization of uncertain fractional-order non-autonomous systems. In this regard, a single input active control approach is proposed for control and stabilization of three-dimensional uncertain fractional-order systems. The robust controller is designed on the basis of fractional Lyapunov stability theory. Furthermore, the effects of model uncertai...
متن کاملMINIMUM TIME SWING UP AND STABILIZATION OF ROTARY INVERTED PENDULUM USING PULSE STEP CONTROL
This paper proposes an approach for the minimum time swing upof a rotary inverted pendulum. Our rotary inverted pendulum is supported bya pivot arm. The pivot arm rotates in a horizontal plane by means of a servomotor. The opposite end of the arm is instrumented with a joint whose axisis along the radial direction of the motor. A pendulum is suspended at thejoint. The task is to design a contro...

In this paper, the problems of robust stabilization and$H_{infty}$ control for uncertain stochastic systems withmultiple time delays represented by the Takagi-Sugeno (T-S) fuzzymodel have been studied. By constructing a new Lyapunov-Krasovskiifunctional (LKF) and using the bounding techniques, sufficientconditions for the delay-dependent robust stabilization and $H_{infty}$ control scheme are p...
متن کاملComparison of the Effect of Scapular Stabilization and Conscious Control Training on Postural Variables, Pain, and Selected Muscle Strength in Patients with Scapular Dyskinesia
Introduction: Scapular orientation and movements can affect the function of the shoulder. Changes in scapular alignment or movement in shoulder regions have the potential to alter the kinetic chain of the body. Therefore, this study aimed at comparing scapular stabilization and conscious control training on postural variables, pain, and selected muscle strength in patients with scapular dyskine...

Uncertain switched linear systems are known as an important class of control systems. Performance of these systems is affected by uncertainties and its stabilization is a main concern of recent studies. Existing work on stabilization of these systems only provides asymptotical stabilization via designing switching strategy and state-feedback controller. In this paper, a new switching strate...
متن کاملFinite-time stabilization of satellite quaternion attitude
In this paper, a finite-time control scheme is presented for stabilization of the satellite chaotic attitude around its equilibrium point when its attitude is confused by a disturbed torque. Controllers and settling time of stabilizaton are obtained, based on the Lyapunov stability theorem and finite-time control scheme. This method is satisfied for any initial condition. Numerical simulations ...
