The good control performance of permanent magnet linear synchronous motor (LSM) drive systems is difficult to achieve using linear controllers because of uncertainty effects, such as fictitious forces. A backstepping control system using adaptive modified recurrent Laguerre orthogonal polynomial neural network uncertainty observer (OPNNUO) is proposed to increase the robustness of LSM drive systems. First, a field-oriented mechanism is applied to formulate a dynamic equation for an LSM drive system. Second, a backstepping approach is proposed to control the motion of the LSM drive system. With the proposed backstepping control system, the mover position of the LSM drive achieves good transient control performance and robustness. As the LSM drive system is prone to nonlinear and time-varying uncertainties, an adaptive modified recurrent Laguerre OPNNUO is proposed to estimate lumped uncertainties and thereby enhance the robustness of the LSM drive system. The on-line parameter training methodology of the modified recurrent Laguerre OPNN is based on the Lyapunov stability theorem. Furthermore, two optimal learning rates of the modified recurrent Laguerre OPNN are derived to accelerate parameter convergence. Finally, the effectiveness of the proposed control system is verified by experimental results.

A resin-made-bellows pump is used practically as a chemical pump application. Its discharge pressure is low as 0.1MPa in general; therefore, its applicable fields are limited. In order to make the pressure higher, we developed a metal bellows pump driven by an electromagnetic reciprocating actuator for various industrial applications with the pressure of over 10MPa and non-leakage performance. As the pressure becomes higher, larger output force is required to the actuator. The developed electromagnetic actuator can drive the bellows by reciprocating motion in the stroke of 1mm with the maximum output force of 1400N. However, the high-speed motion of the actuator by the armature positionand velocity-sensorless control makes issue that the armature collides hard with the stator and generates the noise and vibration. In this paper, the motion control method to reduce the mechanical collision in the actuator without positionand velocity-sensors is presented.

DC motor is a vital component in most of the process control industries. PID controllers are extensively used in DC motors for speed as well as position control. Tuning of PID controller parameters is an iterative process and needs complete optimization to achieve the desired performance. Genetic algorithm (GA) which is a well established tool for optimization has been used to extract PID controller parameters for the velocity control of the DC motor. Different error models are used for evaluating the fitness function. Velocity control is demonstrated using M ATLAB/SIM ULINK modeling.
