3 cards from this section. Quick, good the night before a test.
What does PWM stand for?
Think about how we can vary power to control speed.
What is the purpose of a driver circuit?
Consider the role between the microcontroller and the actuator.
What does PWM stand for?
Focus on how we modify power to control speeds.
True or False: A microcontroller can directly control a high-power actuator.
Consider the roles and capabilities of the components.
Design a closed-loop control system that uses a microcontroller, driver circuit, and an encoder for a robotic arm. Explain how the feedback system would work.
Consider how each component interacts with the rest in processing and responding.
If a PWM signal frequency needs to be adjusted for a new motor, how would you determine the right frequency? Discuss the factors involved.
Think through the relationship between frequency, motor speed, and control efficiency.
