On the Improved Nonlinear Tracking Differentiator based Nonlinear PID Controller Design
This paper presents a new improved nonlinear tracking differentiator (INTD) with hyperbolic tangent function in the state-space system. The stability and convergence of the INTD are thoroughly investigated and proved. Through the error analysis, the proposed INTD can extract differentiation of any piecewise smooth nonlinear signal to reach a high accuracy. The improved tracking differentiator (...
متن کاملDesign of an enhanced nonlinear PID controller
An enhanced nonlinear PID (EN-PID) controller that exhibits the improved performance than the conventional linear fixed-gain PID controller is proposed in this paper, by incorporating a sector-bounded nonlinear gain in cascade with a conventional PID control architecture. To achieve the high robustness against noise, two nonlinear tracking differentiators are used to select high-quality differe...
متن کاملDesign of Observer Based Adaptive Pid Controller for Nonlinear Systems
An observer based adaptive PID controller with micro genetic algorithm (MGA) tuning its parameters is proposed in this paper. The task of the controller is to track the desired trajectory of a nonlinear system as best as it could. The proposed adaptive PID controller consists of 3 components including the PID controller, the control compensating for the external disturbance and the modeling err...
متن کاملGeneralised Nonlinear Pid Controller Based on Neural Networks
In this paper, a nonlinear controller is proposed to handle some nonlinear control problems. In this scheme, the controller uses the system error, the integral of the system error, and the derivative of the system error as its inputs but the mapping from the inputs to the output is nonlinear. The corresponding nonlinear mapping may be specified based on the control requirement. Therefore, the p...
متن کاملNonlinear Controller Design based on Genetic Programming
When designing controllers for linear, time-invariant (LTI) plants, one is limited by the fundamental limitations of linear feedback control. An example of such a limitation is Bode’s gain/phase relationship. The question arises whether these fundamental limitations can be ameliorated by the use of nonlinear feedback. It might seem disadvantageous to introduce nonlinearities in the loop, but an...
