Design Requirements

1. Analyze Technical Parameters and Control Requirements

   • Analyze load characteristics and control requirements.
   • Provide a block diagram of the drive system composition.

2. Select Motor

   • Choose appropriate DC or AC motor rated parameters based on technical parameters and control requirements (calculation required before selection).

3. Design Control Scheme

   • Select suitable motor start, speed regulation, and braking schemes according to control requirements.
   • Analyze the four-quadrant operating points based on motor operation principles and mechanical characteristic curves (lifting the weight from the ground to a high place and then smoothly placing it back on the ground).

4. Build MATLAB Simulation Platform

   • Set motor parameters.
   • Simulate the chosen motor start, braking, and speed control methods using MATLAB.

5. Simulate the Drive System

   • Build a simulation framework for the drive system on the MATLAB simulation platform.
   • Simulate the entire process of lifting and lowering the weight.
   • Debug the system operation, observe changes in key variables (speed, current, voltage, torque), and adjust the control scheme according to load control requirements.
