Integrated Hardware and Software Platform
Supports Development of Industrial Drive and Servo Topology Solutions

Texas Instruments (TI) has launched DesignDRIVE high-speed current loop software that enables C2000™ microcontrollers (MCUs) to implement current loop performance within 1 microsecond.

TI's C2000™ MCU portfolio combined with DesignDRIVE software provides system-on-chip (SOC) functionality that simplifies drive control system development. The new DesignDRIVE high-speed current loop software delivers superior performance compared to conventional microcontroller (MCU) based current loop solutions, and enables implementation without FPGA, which is typically used for external high-speed current control loops, thus simplifying design. The high-speed current loop software is available through a free update to C2000 controlSUITE™.

TI's DesignDRIVE technology is an integrated hardware and software platform that allows engineers to easily develop and evaluate solutions for diverse industrial drive and servo topologies. When developers use the new high-speed current loop software, which is the core of the DesignDRIVE solution, they can achieve high control performance while saving board space and simplifying thermal considerations.

DesignDRIVE has significantly enhanced control loop bandwidth through sub-cycle PWM update technology, resulting in a threefold increase in motor torque response. Additionally, the cycle-scavenging C2000 MCU requires only 460 nanoseconds for field-oriented control (FOC) processing.

Replacing conventional proportional-integral control, the new complex vector-based controller provides high stability at high speeds. Industrial drive systems designed using high-speed current loop software on C2000 MCUs such as the TMS320F28379 can implement SOC functionality to reduce board space, complexity, and overall cost.
