This paper presents the position control of a DC motor using Fuzz Logic and PID Control algorithms. Fuzzy Logic and PID controllers are designed based on labview program, and the real - time position control of the DC motor was realized by using DAQ device. The experimental results demonstrate that the responses of DC motor with FLC show a satisfactory, well damped control performance.
A novel planar magnetic suspension stage has been presented in this paper, a decoupling control approach based on dynamic inversion has used for planar magnetic suspension stage system that is a nonlinear, multivariable and strong coupling system. So this method makes the complicated system becomes simplify and linear. The disturbance has been suppressed by using the disturbance observer. The result...
Aiming at the serious saturation and dead zone nonlinearity, time-variability and time lag existing in pump-controlled cylinder electro-hydraulic servo system droved by SRM (Switched Reluctance Motor) directly, the ILC (iterative learning control) method was put forward to conduct the position servo control for hydraulic machine slider in this thesis. The mathematical model of SRM direct-drive electro-hydraulic...
An variable universe fuzzy control system was designed to control the position of a permanent magnet linear synchronous motor (PMLSM) intelligently considering nonlinear and parameters time-variation. By the analysis of dynamic equation of permanent magnet linear synchronous motors, a position controller for permanent magnet linear synchronous motor is carried out based on the variable universe fuzzy...
In this paper, we introduced a linear motor-based transfer system with an active PID controller which can be replaced with an automated guided vehicle (AGV) for the port automation. This system, which is named LMCTS(liner motor-based container transfer system), is based on PMLSM (permanent magnetic linear synchronous motor) which basically consists of stator modules on the rail and shuttle car. Therefore...
This study presents an adaptive fuzzy controller for linear X-Y table based on FPGA (Field Programmable Gate Array) technology. The linear X-Y table is driven by two PMLSMs (Permanent Magnet Linear Synchronous Motors). Firstly, a mathematic modeled for PMLSM drive is defined. Secondly, to increase the performance of the PMLSM drive system, an AFC (Adaptive Fuzzy Controller) constructed by a fuzzy...
A linear switched reluctance motor (LSRM) based position tracking system and its control aspect are presented in this paper. Based on modeling analysis of the drive system, two reduced order controlled models are developed with different time scales, referred as mechanical subsystem and electrical subsystem. Two controllers are respectively designed for the two subsystems. Simulation results demonstrate...
The problem of designing global robust sliding mode controller is considered for position tracking of DC motors with nonlinearities. Fast, the exact linearization technique is used to transform the nonlinear system into a linear one, and then global robust sliding mode control strategy is adopted to solve the system uncertainty problems. The integral sliding surface can effectively remove reaching...
The position control problem of motor-load system is considered, and switched PID controllers are designed for different reference input signals. A new PID design method is developed according to model-matching principle and the problem of PID controller design is converted into fitting problem of magnitude-phase curve for restricted frequency range, first, the second-order reference model is selected...
An Hinfin robust controller based on local feedback recurrent neural network (RNN) is proposed for the position tracking control of the permanent magnet linear synchronous motor (PMLSM). The proposed local feedback RNN with a simple-architecture is employed to estimate dynamic mapping of lumped element uncertainty. Based on the result of RNN, the quadric form function of the Hinfin robust controller...
The speed or the position synchronization is required for some industrial equipments, such as rolling machine and gantry crane, driven by the servo-motor driver in order to carry the cooperative job. When we design the synchronizing controller by using the commercial servo-amp, it is necessary to obtain its system parameters which are generally unknown. In this paper, the equivalent model of the commercial...
