In this 9th lecture of the motor control course we discuss open loop control system and how to build a Simulink model to allow us to control the BLDC motor without closing the speed control loop. We start from the models developed in previous lecture and by putting together all these models we will spin up for the first time the BLDC motor based on Hall sensor commutation. 


Main topics:

    - What is Open Loop Control system and how is it different from a Closed Loop Speed Control system ;

    - Build the Simulink model for Open Loop control of BLDC motor;



    - Understand the benefits of Open Loop Control system;

    - Validate all the concepts we learn so far;   

    - Apply and reuse all the models we developed so far in this course;

    - Spin the motor for the first time;
