This paper reviews the important recent research contributions for control of machining processes {e.g., turning, milling, drilling, and grinding). The major research accomplishments are reviewed from the perspective of a hierarchical control system structure which considers servo, process, and supervisory control levels. The use and benefits of advanced control methods (e.g., optimal control, ...
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. This paper presents an approach towards the control system tuning for the speed control of an AC servo motor. An approach towards speed control of servo motor in presence of system parameter variations is presented....
In this study, an adaptive fuzzy sliding-mode control (AFSMC) system is adopted to control the position of an induction servo motor. The AFSMC system comprises the fuzzy control design and the robust control design. In the fuzzy control design a fuzzy controller is designed to mimic an ideal control law. In the robust control design a robust controller is designed to compensate the approximatio...
This chapter introduces visual servo control, using computer vision data in the servo loop to control the motion of a robot. We first describe the basic techniques that are by now well established in the field. We give a general overview of the formulation of the visual servo control problem, and describe the two archetypal visual servo control schemes: image-based and position-based visual ser...
Constrained optimal control can be remarkably challenging to control. In this paper, optimization based approach for constrained optimal control of the integrating process is investigated through inventory control from using of the PI controller in the servo problem. The Lagrangian multiplier method is applied to find the PI parameters by solving the constrained optimal problem. The developed m...
A method constructing vacuum servo control system with a combined vacuum generator is proposed and the single neural adaptive PID control strategy is also proposed due to the inherent defects of the vacuum servo system in this paper. The influence of the system parameters to the characteristics of the vacuum servo system is analyzed and discussed. The simulation and the experiment show that the...
Abstract: Today’s motor drives widely use Digital Signal Processor (DSP) or Microcontroller to implement the digital control algorithm. Most recently new requirements have arisen. These include faster torque control update with flexible design capability of motion peripherals for high performance military servo drive applications. A Complete digital hardware based AC servo drive development sys...
The performance of the pneumatic servo systems improved greatly as the pneumatic servo valves became commercially available in the late 1980s. At present, one of the best pneumatic servo valves has a dynamic response of 100 Hz and a spool position accuracy of 2% to the full stroke. By using these pneumatic servo valves, the precise position control by the pneumatic servo system has entered a pr...
The problem being taken up is, the speed servo control of a PMDC motor. The reference input is continuously changing and also the load torque on the motor shaft is continuously varying. A control law based on the load torque is proposed. The Computed Torque Control scheme is used. The load torque, being of unknown kind, cannot be sensed and hence it has to be estimated. The load torque is estim...
