To design and implement the additive controller for permanent magnet brushless dc motor drive in sensor-less control technique for dSPACE controller for Robot movement control. Further the estimation technique for Back-EMF in feedback loop holds better dynamic performance during knee movement in various case loops.In this study algorithm estimates feedback loop valuesto control position and angular speed of the BLDC motor as action part for knee movement. Further this method estimated rotor position and flux information based on initial position of the rotor through Hall feedback signals and encoder pulse. Feedback loop drive eliminated to track the dynamics drive and control logic modeled in MATLAB/SIMULINK and the source code built in MATLAB and loaded onto the dSPACE controller. Proposed control algorithm with improves back-EMF estimation accuracy and rotor position accuracy. Further proposed estimation sensor-less technique enhances capture position parameters at low speed. Additive algorithm and PLL method is simple to implement in MATLAB and configure in dSPACE controller to maintain high stability. An intelligent power module used to drive the BLDC motor through pulse width signals to controller and drive converter for BLDC motor to operate. The proposed algorithm implemented for PMSM motor drive in wind turbine applications due nature of back-EMF estimation. Further this algorithm method can be implemented with high processing controller for low cost drive applications.
