Stabilization of the Inverted Pendulum with Backlash Using $H_{infty}$-LMI Technique
نویسندگان
چکیده
The rotary inverted pendulum, also named Furuta Pendulum, has been studied extensively for control performance evaluation in under-actuated mechanisms. The H∞ control invoking Linear Matrix Inequality (H∞-LMI) has been also wide employed for linear control design. This paper deals with the feasibility ofH∞-LMI technique to stabilize the rotary inverted pendulum around its unstable equilibrium point when there exists a backlash nonlinearity in the actuator. So, the H∞-LMI design faces the nonlinear effect in the actuator and the non-linear pendulum model. Experimental realization of the designed H∞-LMI control evidences the good performance of the controller subject to external perturbation too.

Delay-dependent robust stabilization and $H_{infty}$ control for uncertain stochastic T-S fuzzy systems with multiple time delays
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...

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 we consider the problem of delay-dependent robustH1 control for uncertain fuzzy systems with time-varying delay. The Takagi–Sugeno (T–S) fuzzy model is used to describe such systems. Time-delay isassumed to have lower and upper bounds. Based on the Lyapunov-Krasovskiifunctional method, a sufficient condition for the existence of a robust $H_{infty}$controller is obtained.

In this article, we investigate an elastic inverted pendulum with hysteretic nonlinearity (a backlash) in a suspension point. Namely, problems of stabilization and the optimization of such a system are considered. An algorithm (based on a bionic model) which provides effective procedure for finding of optimal parameters is presented and applied to considered system. The results of numerical sim...
متن کاملElimination of Hard-Nonlinearities Destructive Effects in Control Systems Using Approximate Techniques
Many of the physical phenomena, like friction, backlash, drag, and etc., which appear in mechanical systems are inherently nonlinear and have destructive effects on the control systems behavior. Generally, they are modeled by hard nonlinearities. In this paper, two different methods are proposed to cope with the effects of hard nonlinearities which exist in friction various models. Simple inver...
