Position Control System

The development of a position control system using a stepper or incremental motor is described. The advantages of this type of prime mover are discussed, and a technique of integrating the stepper motor into the system is analyzed. The output signal from the error detector used in the system comes from a sampler and zero-order hold circuit. This signal controls a gate which either allows or inhibits a pulse train to drive the stepper motor. The load on the motor is an underdamped second-order system. The stepper motor output position and the reference input determine the error. The analysis includes a stability investigation using the describing-function method and a computer simulation to determine the dynamic performance of the system. The effects of noise in the system are also investigated on the computer. The equipment used to mechanize the control system is described, and results of experimentol work to determine the actual performance of the system are given.

Position Control System

<p>This paper presents a multiple unipolar stepper motor position control system using microcontroller (MCU) in anticlockwise and clockwise directions. The open loop controller of the implemented position control system for the three stepping modes of operation has been designed and developed with three stepper motors and without position feedback. The MCU is programmed using flowcode software package to generate the pulse signals with the desired stepping sequences and step angles. These pulse signals are necessary to drive the three stepper motors in the three drive modes (wave-step, full-step, and Half-step) according to the control algorithm. Three devices of 8 Channel Darlington Driver (chip ULN2803) are used to drive the three stepper motors and provide them with the sufficient current. The position control system has been simulated using proteus design suite software package and the controller has been implemented using low cost PIC16F877A (MCU). A reliable and accurate position control of the stepper motor is achieved by this position control system. </p>

Position Control System

In order to obtain much better control effect, position control system uses position-speed dual closed loop structure in the testing system of hard air refuel tanker drag system. According to the characteristics of nonlinear system, PID controller and fuzzy controller were taken as the outer loop controllers. The simulation results show that the fuzzy control system is superior to PID control. By comparing response curves with different load, it is easy to see that fuzzy control can be more effective than PID control in restraining overshoot and improving the dynamic performance.

Two Degree Of Freedom

Background: The conventional method using one-degree-of-freedom (1DOF) controller for Permanent Magnet Synchronous Motor (PMSM) servo system has the trade-off problem between the dynamic performance and the robustness. Methods: In this paper, by using H∞ control theory, a novel robust two-degree-of-freedom (2DOF) controller has been proposed to improve the position control performance of PMSM servo system. Using robust control theory and 2DOF control theory, a H∞ robust position controller has been designed and discussed in detail. Results: The trade-off problem between the dynamic performance and robustness which exists in one-degree-of-freedom (1DOF) control can be dealt with by the application of 2DOF control theory. Then, through H∞ control theory, the design of robust position controller can be translated to H∞ robust standard design problem. Moreover, the control system with robust controller has been proved to be stable. Conclusion: Further simulation results demonstrate that compared with the conventional PID control, the designed control system has better robustness and attenuation to the disturbance of load impact.

The Stability

The control system performance requirement was divided into three parts. They were the stability, rapidity and accuracy. The time-frequency domain analysis in the requirements of three performance were measured through quantitative performance index. The mutual restriction of time-frequency performance and system characteristic parameters of normal second order was discussed. The correlation of system time-frequency performance index was established. The relationship between time-frequency performance indexes in standard two order system was extended to higher order system. The mutually constraining and time-frequency correlation between each performance index was obtained by analysis and calculation. The work had been done above had practical significance to reflect the system dynamic performance in different analytical domains.
