This paper introduces a high performance DC chopper speed and current control system for universal motors. Differing from existing TRIAC and DC chopper speed control schemes, the new system adds the inner current control to improve dynamic response, and the motor starts up with closed speed and current control loops. Complete control schemes have been developed and implemented in a low cost Renesas...
An AC slip-ring motor speed estimation in the industrial crane control system is realized. Speed estimation is based on the rotor voltage frequency measurement. For the hardware implementation, ADMC300 DSP based unit is used. Speed estimation unit is included in the modular structure of the industrial crane control system. Authors investigate speed estimation algorithm solutions and implication of...
