Design of Airborne Radar Servo Control System

Control System Design of a Pneumatic Servo System

Pneumatic servo systems are applied in several industrial applications and have also been studied extensively for the purposes of compensating the nonlinearity of pneumatic servo systems and improving the controllability with robust control. In their control system design, the transfer function of a pneumatic servo system has been a third-order time lag system, based on the assumption that serv...

Velocity Control of Electro Hydraulic Servo System by Tracking Method

This paper proposes an efficient Tracking method for velocity control of an electro-hydraulic servo system (EHSS) in the presence of flow nonlinearities and internal friction. The tracking method controller is a kind of feedback error learning structure. In the proposed method, the Feedback Error Learning (FEL) algorithm is used to control the velocity. There is no need to compute the system ja...

Multimode/Multifrequency Low Frequency Airborne Radar Design

This work deals with the design of multimode/multifrequency airborne radar suitable for imaging and subsurface sounding. The system operates at relatively low frequencies in the band ranging from VHF to UHF. It is able to work in two different modalities: (i) nadir-looking sounder in the VHF band (163MHz) and (ii) side-looking imager (SAR) in the UHF band with two channels at 450MHz and 860MHz....

Control System Design for a New Servo Press

A control system is developed for controlling a newly designed 300-ton servo press. The control goal is to drive the punch to track various desired trajectories, and to ensure the accurate repeatability of its bottom-dead-centre (BDC). Two major difficulties are encountered in designing the system. The first one is the nonlinear kinematics of the force-amplification mechanism. The second is the...
