RISOn the Design of Adaptive Servosystems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with tracking problems in which the plant is single-input single-output and the desired trajectory (command signal) is regarded as the output of an unknown free dynamical system. ...
A Simple Digital Control Scheme for a Class of Multi-Input, Multi-Output Industrial Processes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with digital control of m-input, m-output industrial processes. The controller design is based on two kinds of mathematical process models which can be obtained from the process ...
Modeling and Conventional/Adaptive PI Control of a Lathe Cutting Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mathematical model for predicting dynamics between the feedrate and cutting force in the lathe cutting process is presented. The model comes from combinations of a parameter identification ...
Application of Learning Control to Active Damping of Forced Vibration for Periodically Time Variant Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with discrete time learning controllers for systems with periodically varying parameters. Several control rules are proposed which use a basic principle of learning control that ...
The Effect of Adding Zeroes to Feedforward Controllers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of adding zeroes to two types of feedforward controllers, stable pole zero cancelling (SPZC) controllers and zero phase error tracking (ZPET) contollers, is discussed. When there are ...
Deterministic Disturbance Rejection in Linear Identification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Adverse effects of deterministic disturbances in linear identification are pointed out. The deterministic disturbance rejector (DDR) is introduced to remove such effects in discrete-time series-parallel ...
Vehicle Lateral Velocity and Yaw Rate Control With Two Independent Control Inputs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In automatic lateral control, which will play a key role in highway automation, vehicles must follow a given path and vehicle direction must be controlled as desired. Therefore, the ideal is ...
A Suboptimal Reference Generation Technique for Robotic Manipulators Following Specified Paths
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The optimal reference generation problem deals with finding a tracking velocity versus time profile which will move the end effector of a multiple degree of freedom robotic manipulator through ...
Feedforward Tracking Controller Design Based on the Identification of Low Frequency Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Several methodologies are proposed for identifying the dynamics of a machine tool feed drive system in the low frequency region. An accurate identification is necessary for the design of a ...
Optimal Discrete Finite Preview Problems (Why and How Is Future Information Important?)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The preview control problem is one in which a controller can use future as well as present and past information to determine the control. In the optimal discrete finite preview problem studied ...
