1) The strengths and weaknesses of DC servo motors
Advantages: speed control, torque and speed characteristics are very hard, the control principle is simple, easy to use, and cheap.
Defects: Brush commutation, speed limit, additional resistance, occurrence of wear particles (not suitable for dust-free and explosive environments)
2) The strengths and disadvantages of AC servo motors
Advantages: good speed control characteristics, smooth control can be completed in the entire speed area, almost no oscillation, more than 90% of the rate, less heating, high-speed control, high degree of position control (depending on the accuracy of the encoder), in the rated operation area, constant torque, low inertia, low noise, no brush wear, maintenance-free (suitable for dust-free, explosive environment).
Defects: The control is messy, the driver parameters need to be adjusted on the spot to confirm the PID parameters, and more connections are required.
At present, the mainstream servo drives all use digital signal processors (DSPs) as the control core, which can complete the messy control algorithms and complete digitalization, networking and intelligence. Power devices generally use the intelligent power module (IPM) as the core planning of the drive circuit, IPM internal integration of the drive circuit, at the same time with overvoltage, overcurrent, overheating, undervoltage and other fault detection and maintenance circuits, in the main circuit also participate in the soft start circuit, in order to reduce the impact of the start-up process on the driver. The power drive unit mainly rectifies the input three-phase electricity or mains power through the three-phase full-bridge rectifier circuit to obtain the corresponding direct current. The three-phase permanent magnet synchronous AC servo motor is driven by the rectified three-phase electricity or mains power, and then the three-phase sinusoidal PWM voltage inverter is used for frequency conversion. The whole process of the power drive unit can be simply said to be the process of AC-DC-AC. The main topology circuit of the rectifier unit (AC-DC) is the three-phase full-bridge uncontrolled rectifier circuit.

Obstacle avoidance control of the manipulator – KUKA robots
The kinematic redundancy of freedom of the manipulator means that the manipulator has more degrees of freedom than is required at the end of the manipulator. Kinematic manipulators with redundant degrees of freedom have better functions than manipulators with non-redundant degrees of freedom. For example, a manipulator with non-redundant degrees of freedom has obstacles in the external environment.
