This paper presents a hybrid control scheme for the aircraft automatic landing system. PID control law is adopted in the controller design. Disturbance adaptive capability is demonstrated through hardware in the loop simulations. The control scheme uses PID controller with evolutionary computation technique. Control gains are selected by real-valued genetic algorithms. Different crossover metho...

This paper gives a framework of supervisory control of boiler drum level system. The design and implementation of this process is done by the LabVIEW software. The data of the process variables Level from the boiler system need to be logged in a database for further analysis and supervisory control. A LabVIEW based data logging and supervisory control program simulates the process and the gener...

PID control schemes have been widely used in most process control systems for a long time. However, it is a very important problem how to choose PID parameters. Because these parameters give a great in uence on the control performance. Especially, it is dif cult to tune these parameters for time-varying systems. In this paper, performance adaptive controller is proposed for such systems, which ...

The purpose of this paper is to present a new adaptive control method used to adjust the output voltage and current of DC-DC (DC: Direct Current) power converter under different sudden changes in load. The controller is a PID controller (Proportional, Integrator, and Differentiator). The gains of the PID controller (KP, KI and KD) tuned using Simulated Annealing (SA) algorithm which is part of ...

For a class of robot arms, a proportional derivative (PD) controller plus gravity compensation yields the global asymptotic stability for regulation tasks, and some proportional-integral-derivative (PID) controllers guarantee local regulation without gravity cancellation. However, these controllers cannot render asymptotic stability for tracking tasks. In this paper, a simple decentralized cont...

This paper suggests an auto-tuning method of PID trajectory tracking controller for robotic manipulators. In general, the PID trajectory tracking controller for mechanical systems shows the performance limitation. Since the control system including performance limitation can not have equilibrium points, we define newly the quasi-equilibrium region as an alternative for equilibrium point. Also, ...

This paper presents a hybrid control strategy, combining Radial Basis Function (RBF) network with conventional proportional, integral, and derivative (PID) controllers, for the greenhouse climate control. A model of nonlinear conservation laws of enthalpy and matter between numerous system variables affecting the greenhouse climate is formulated. RBF network is used to tune and identify all PID...

Introduction Focused ultrasound induced heating for use in thermal therapy requires reliable temperature control to assure safety and therapeutic accuracy. MR thermometry based on the proton resonance frequency shift (PRFS) [1] in combination with a proportional, integral, derivative (PID) feedback control [2] has been suggested as a precise solution for controlling high intensity focused ultra...
