Functional OverviewThe DS200DSPCH1ADA is a 24-channel discrete (digital) input module in the GE Mark VIe control system. Its primary function is to collect discrete signals (contact open/close signals) generated by field devices such as sensors,
switches, and relays, convert them into digital signals that can be recognized and processed by the PLC or control system CPU,
and transmit the processed data to the GE Speedtronic turbine control system or other control equipment, enabling automated control and monitoring. Key Technical Specifications

Distinguished according to whether there is a position sensor, first of all, it is divided into sensing and non-sensing. That is, whether Hall or other similar position sensors are used to sense the position angle of the stator and rotor. In air pump applications, many use non-inductive control. The excellent algorithm of through-hole is that after the motor is running, it detects the changes in phase current to switch the phase current. In some heavy-duty or precise control applications, sensory methods are used.
According to the three-phase power supply of the inverter, it can be divided into square wave control and sine wave control. The square wave control strategy is simple, and the control process is direct and effective. It adopts a six-step commutation strategy. The CPU modulates the PWM to drive the power switch tube to generate a three-phase power supply that can run the motor. The control strategy of sine wave is relatively complex, but the control effect is much better.
In sine wave control, there are two main control strategies.
One is direct torque control DTC Baidu Encyclopedia. The method is to calculate the estimated values of motor flux and torque based on the measured motor voltage and current. After controlling the torque, the motor speed can also be controlled. Direct torque control is a patent of the European ABB company. .
The second is, space vector control FOC Baidu Encyclopedia. Its essence is to equate an AC motor to a DC motor, and independently control the speed and magnetic field components. By controlling the rotor flux linkage, and then decomposing the stator current, the two components of torque and magnetic field are obtained. After coordinate transformation, the normal motor is realized. handover or decoupling control.
During sine wave control, there are many derived more sophisticated control strategies, such as feedforward control, maximum torque control, field weakening control, etc.
In the process of controlling the motor, there are multiple feedback control loops. When controlling the output of the motor, there is a current loop; on this basis, there is a control loop that controls the speed; when a servo motor is used, there is a position loop control.
