PID Control: New Identification and Design Methods - [Book Review]

Abstract: FEBRUARY 2006 « IEEE CONTROL SYSTEMS MAGAZINE 95 CONCLUSIONS This book, written by some of the main contributors to the subject, covers an important new perspective on PID control. The book is of interest to practicing engineers, graduate students, and researchers working in the systems and control area. The materials are understandable to average readers with a basic knowledge of systems and control. The book is very well written and can be used for self-study and as a reference. Keqin Gu

Chattering free sliding mode control law for the drive employing PMSM position control

Abstract: The control system for position control of the drive employing PMSM based on the principles of sliding mode control and respecting the principles of vector control is presented. Designed controller is chattering free and complies with demanded control precision. Described control technique divides PMSM into two channels, which enable to control motor flux and torque separately. The controller is of the parallel structure, comprising a control loop for control of machine magnetic flux and parallel loop for control of the machine torque and rotor angle. To achieve demanded precision and to eliminate control chattering a smoothing integrator is introduced into both parallel controllers and furthermore the signnm function is replaced by a proportional high gain in the final version of the controllers. The simulations and preliminary experimental results indicate that the control systems yield the desired robustness and more complex investigations are recommended.

Joint-space adaptive control of a redundant telerobot manipulator

Abstract: The design of a joint-space adaptive control-scheme for controlling the slave arm motion of a dual-arm telerobot system developed to study the telerobotic operations in space is presented. Each slave arm of the dual-arm system is a kinematically redundant manipulator with 7 degrees of freedom (DOF). Using the concept of model reference adaptive control (MRAC) and the Lyapunov direct method, the authors derive an adaptation algorithm which adjusts the PD (proportional and derivative) controller gains of the control scheme. The development of the adaptive control scheme assumes that the slave arm motion is noncompliant and slowly varying. The implementation of the derived control scheme does not require the computation of manipulator dynamics which makes the control scheme sufficiently fast for real-time applications. A computer simulation study performed for the 7-DOF slave arm shows that the developed control scheme can efficiently adapt to sudden change in payloads while tracking various test trajectories such as ramps or sinusoids with negligible position errors. >

Adaptive Cruise Control System using Balance-Based Adaptive Control technique

Abstract: In this paper, a nonlinear Balance-Based Adaptive Control (B-BAC) technique is proposed for the design of an Adaptive Cruise Control (ACC) System. The architecture for ACC system represents the cascade control and it includes two control loops. The B-BAC technique accounts for system nonlinearities and it allows for split range control of both the brake and the throttle so it can be utilized in the design of the inner-loop control, while the outer-loop control is based on a simple proportional controller. The results of the simulation prove the effectiveness of the proposed algorithm in distance and speed tracking as well as providing the smooth variation of the vehicle acceleration.
