  • It is important to have speed control of motors on UAVs since the system dynamics are related to the rotation speed of the motors. This paper presents a sensorless phase voltage detection scheme to measure the rotation speed. A PID controller is implemented to ensure the performance of the motors. A mathematical model of Delta-Connected BLDC motors is built for analyzing the relationship between phase voltage and rotation speed.

  • Preface are not communicated to the people who must apply them. Control problems arise in the plant and must be solved in the plant. Until plant engineers and control designers are able to communicate with each other, their mutual problems await solution. I do not mean to imply that abstract mathematics is not capable of solving control problems, but it is striking how often the same solution can be reached by using good common sense. High-order equations and high-speed computers can be manipulated to the point where common sense is dulled....

  • This chapter introduces two-inductance, T and T', per-phase equivalent circuits of the induction motor for explanation of the scalar control meth-ods. The open-loop, Constant Volts Hertz, and closed-loop speed control methods are presented, and field weakening and compensation of sup and stator voltage drop are explained. Finally, scalar torque control, based on decomposition of the stator current into the flux-producing and torque-producing components, is described.

  • Typical dynamic responses are also shown. The motor is initially at standstill and at no load when a step command in speed is applied; when steady-state conditions are reached, a reversal of speed is commanded followed by a step load application. The system is highly nonlinear due to the introduction of saturation needed to limit both the current delivered and the voltage applied to the motor.

  • This paper describes a new solution to control the induction motor drive system without current sensors based on improving the Hysteresis Pulse Width Modulation technique. It has proposed a control scheme which uses stator currents estimated from the differential equation of state variables to replace the feedback signal from current sensors applied in the hysteresis current controller.

  • The satellite is supposed to move in a circular orbit around the Earth and always require energy for its activities. Therefore, the solar panels need to orient towards the Sun as long as possible to receive the most energy. In the first step, a dynamics model of a satellite disposed by three momentum wheels whose angular speeds controlled by corresponding motors is developed.
