Abstract: A servo control system with a three-closed-loop control structure for permanent magnet linear synchronous motor(PMLSM) is constructed based on the mathematical model of PMLSM. The voltage space vector control strategy is adopted to build a overall simulation model of the servo control system for PMLSM in MatLab/Simulink environment. The results of the experiments are analyzed and proves the correctness of the simulation model which provides a basic model for the subsequent research on the control method of high-precision PMLSM.

Abstract: An intelligent auto-tracking car based on DC motor control is designed in this paper, which uses the photoelectric sensors at the front and the left and right sides of the car to detect the black line on the runway, STC12C5A MCU as the core to control the motor for adjusting the direction of the car, and the PWM signals to adjust the speed, so as to realize the car driving along the runway and the function of overtaking. The tracing information acquisition part is composed of the reflective photoelectric sensors and the comparator, which processes the collected data and sends them to the MCU. The control of motor speed is realized by using PWM wave output from SCM to realize the intelligentialize of the car. The car has automatic tracking, starting point detection and automatic sound alarm and other functions. Based on stable hardware circuit design and accurate and reliable software algorithm, the car can realize the expected function.

Abstract: In order to solve the problems of traditional inductance balanced circuits, such as one-way-flow energy between batteries, low efficiency, complex structure and so on, a new balanced circuit topology is presented in this paper, which can transfer electric energy from high voltage battery unit to low voltage battery to achieve the balance between batteries. In order to ensure that the electric energy can achieve two-way-flow and the balanced current can work in continuous state, the classic Buck-Boostcircuit is improved at first as a balancing unit for series battery pack. Then, the duty cycle of each switching is calculated according to the characteristics of the balancing circuit to complete electric energy flowing from the high to the low in the series battery pack. Secondly, the balanced current value is derived by analyzing the circuit. Finally, the simulation experiments are done on Simulink platform, and the effectiveness of the balanced circuit is proved.

Abstract: The mathematical model of optical pod pitch is established by using the system identification method. The controller parameters of fractional order PIλDμare tuned based on the amplitude margin and phase margin method, and the AL-Alaoui+CFE impulse response invariant method is used to discretize the controller. Finally, the model is simulated and analyzed with Kalman filter, and the results show that the fractional order PIλDμcontroller based on the Kalman filter has better control effect, stronger robustness and anti-interference ability than pure fractional order PIλDμcontroller.
