Model-free PID controller optimization for loop shaping
نویسنده
چکیده
In this paper, a data-driven model-free design method of PID controller is proposed for a single-input single-output linear time-invariant plant for a loop shaping problem where the integral gain is maximized under the maximum sensitivity constraint. This design problem is reduced to a linear programming problem. The constraints on the PID gains are given from many fictitious data, which are obtained by applying the wavelet transform to a step response. Our design method does not require the iteration of modeling and control design and the performance index refinement. Numerical examples show the robustness against measurement noise.

Optimization of fuzzy controller for an SMA-actuated artificial finger robot
The purpose of this paper is to design and optimize an intelligent fuzzy-logic controller for a three-degree of freedom (3DOF) artificial finger with shape-memory alloy (SMA) wire actuators. The robotic finger is constructed using three SMA wires as tendons to bend each phalanx of the finger around its revolute joint and three torsion springs which return the phalanxes to their original positio...

In this paper, a new technique called robust loop shaping–fuzzy gain scheduled control (RLS–FGS) is proposed to design an effective nonlinear controller for a long stroke pneumatic servo system. In our technique, a nonlinear dynamic model of a long stroke pneumatic servo plant is identified by the fuzzy identification method and is used as the plant for our design. The structure of local contro...

In this paper, a robust controller design method is first formulated to deal with both performance and robust stability specifications for multivariable processes. The optimum problem is then dealt with using a loop-shaping H∞ approach, which gives a sub-optimal solution. Then a PID approximation method is proposed to reduce a high-order controller. The whole procedure involves selecting severa...

متن کاملGlobal Controller Optimization Using Horowitz Bounds
A procedure for global optimization of PID type controller parameters for SISO plants with model uncertainty is presented. Robustness to the uncertainties is guaranteed by the use of Horowitz bounds, which are used as constraints when low frequency performance is optimized. The basic idea of both the optimization and the parameter tuning is to formulate separate criteria for low, mid and high f...
