This paper proposes a new approach to disturbance estimation based on a curvature model to improve the disturbance rejection performance of a servo system. The main feature is that the stability of the control system is guaranteed when the disturbance estimation is incorporated directly into the designed control law. Simulation results show that disturbances are rejected efficiently when this a...
This paper presents a survey of control issues in optical storage data systems. Servo control has the important role of moving the optical pick to a track and regulating it to read and write data along the track. The performance of the servo system determines total system performance, such as access time, data rate, and latency. In this regard, we review servo control systems and walk readers t...
AC servo systems are extensively used in robotic actuators and are competing with DC servo motors for motion control because of their favorable electrical and mechanical properties. Efficient control schemes for servo motors are required to ensure performance in presence of system parameter variations. Neural networks have emerged as a suitable tool for control applications especially under sit...
This article is the first of a two-part series on the topic of visual servo control—using computer vision data in the servo loop to control the motion of a robot. In the present article, we describe the basic techniques that are by now well established in the field. We first give a general overview of the formulation of the visual servo control problem. We then describe the two archetypal visua...
A servo manipulator system has been developed for remotely handling radioactive materials in a hot cell [1]. Unlike a robot manipulator, a servo manipulator is monitored and controlled by an operator all the time. A robot manipulator performs a taught or programmed task without an operator. Generally, a servo manipulator consists of a master arm and a slave arm. The slave arm is a device for wo...
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...
This chapter utilizes the direct neural control (DNC) based on back propagation neural networks (BPN) with specialized learning architecture applied to the speed control of DC servo motor. The proposed neural controller can be treated as a speed regulator to keep the motor in constant speed, and be applied to DC servo motor speed control. The proposed neural control applied to position control ...
Nonstationary Optimal Servo Control Realizing Smooth Switching from Velocity Servo to Position Servo
the ball and beam system is one of the most popular laboratory setups for control education. in this paper, we design a fuzzy pd cascade controller for a ball and beam system using asexual reproduction optimization (aro) technique. the ball & beam system consists of a servo motor, a grooved beam, and a rolling ball. this system utilizes a servo motor to control ball’s position on the beam. chan...
To enhance the tracking accuracy of servo control system of a testing platform, the AC servo control system digital controller based on DSP is designed, and the structure and the working principle of the system are introduced in this article. For system hardware, TMS320F28335 is the control core, and for the software, complex control strategy of PID control and feed-forward control is adopted. ...
