Built upon TI’s InstaSPIN™-FOC motor control solution, InstaSPIN-MOTION is uniquely designed to optimize complex motion sequences, reduce tuning to a single parameter and tracking desired trajectories with unmatched accuracy across operating ranges. It constitutes the easiest and most effective method for achieving optimized sensorless motor control.
TI’s InstaSPIN-FOC solution, which was announced earlier this year, takes advantage of the FAST™ premium software sensor for rotor flux measurement and provides motor identification, automatic current control tuning and sensorless feedback in a field-oriented control torque controller and speeds deployment of efficient, sensorless, variable load three-phase motor solutions.
InstaSPIN-MOTION further improves motor performance and development time
Adding additional motor control functionality, InstaSPIN-MOTION enables more expertise on chip. With the core algorithms embedded in the read-only-memory on TI’s 32-bit C2000 Piccolo microcontrollers, InstaSPIN-MOTION integrates SpinTAC components from LineStream Technologies, featuring optimized motion profiling, single-parameter tuning and a disturbance-rejecting controller, which speeds development and increases performance across changing speeds and loads. InstaSPIN-MOTION can be used with sensored feedback or with the included sensorless InstaSPIN-FOC solution.
InstaSPIN-MOTION features and benefits:
• Eliminate motion control challenges in traditional motor systems. InstaSPIN-MOTION removes the need for inefficient, older design techniques. For example, defining the motor’s desired motion in other methods requires simplistic, inflexible trajectories, resulting in mechanical stress. Hand-coded, calculation-heavy trajectories consume valuable memory. Likewise, achieving desired motor performance across varying conditions requires multiple sets of multi-parameter, proportional-integral controllers needing time-intensive tuning.
• InstaSPIN-MOTION’s SpinTAC components include:
– IDENTIFY: Ensure optimum tracking and disturbance rejection, working with the real inertia of the system.
– CONTROL: Minimize effort and reduce complexity with single coefficient tuning. Rapidly test and tune velocity control from soft to stiff response, defining a controller gain that typically works across the entire variable speed and load range of an application. Actively estimate and cancel system disturbances in real time, providing maximum performance.
– MOVE: Produce an automatically optimized motion profile based on start velocity, target velocity and system limitations for acceleration, jerk and motion trajectory type.
– PLAN: Quickly build various states of motion (speed A to speed B) and tie them together with state-based logic.
• Develop and evaluate quickly using the new motor control software infrastructure, MotorWare. Take advantage of modules, drivers, system examples and documentation representing the latest in C object-oriented and API-based coding techniques.
