Control Engineering Fundamentals Chapter 2 Answer

1. The three figures in Figure (Question 3) represent three respectively A mechanical system. Find their respective differential equations. In the figure, xi represents the input displacement and xo represents the output displacement. Assuming that the output has no load effect.

2. Solution: 2-3 Find the transfer function shown in the figure (Question 2-3), and write the expression of the non-damping natural frequency and damping ratio of the two systems.Solution: The figure has: The figure has: ∴2-4 Find the transfer function of the mechanical system shown in the figure (Question 2-4). The figure shows the input torque, circumferential damping, and the rotational inertia.

3. The basic mode of control Open-loop control: The output of the system has no control effect on the system, or the system without a feedback loop in the system is called an open-loop control system. Closed-loop control: The output of the system has a controlling effect on the system, or a system with a feedback loop in the system is called a closed-loop control system.

4. Control Engineering Basic Review Question A Judgment (1). The ratio of the Lash transform output by the linear system to the input Lah transform is defined as the transfer function of the system. ( ×) (2). The free motion mode of the system is jointly determined by the poles and zeros of the system.

Electromechanical Transmission Control Feng Qingxiu Deng Xingzhong Fifth Edition Exercises and Answers

1. Electromechanical Transmission Control Feng Qingxiu Deng Xingzhong Fifth Edition Exercises and Answers Chapter 2 Dynamics Fundamentals of Electromechanical Transmission System 1 Description The concepts of drag torque, static torque and dynamic torque in the equation of motion of the electromechanical transmission system. Drag torque is generated by an electric motor to overcome the load torque to drive the movement of production machinery.

What is the motion control system

The motion control system refers to changing the torque, speed, displacement, etc. of the working machinery through the precise control of the voltage, current, frequency and other input power of AC and DC motors.The amount of machinery makes all kinds of machinery run according to the requirements of people's design to meet the needs of production technology and practical application.

is the control process of an object in the running process. There are: mechanical transmission control, through PC control, it can analyze the action and direction of the operating object during operation, which is also the so-called robot control system.

Motion control system is a kind of automatic control system, which is an automatic control system specialized in motion control.

The automatic control system is divided into two categories according to its different control objects.

How does the Jacobi matrix affect the motion planning and control system?

Control system: In the control system, the Jacobi matrix is used to describe the state space model of the system.By solving the Jacobi matrix, the input and output relationship of the system can be determined, so as to realize the control of the system. Optimization theory: In optimization theory, the Jacobian matrix is used to describe the gradient of the target function.

Control theory: In control theory, we need to design a controller to achieve precise control of the system. In order to achieve this goal, we need to understand the state space model of the system and the impact of the controller on the system state. The Jacobian matrix plays a key role here.

The function of the Jacobian matrix is that it embodies the optimal linear approximation of a differentiable equation and a given point. Use the Jacobi matrix to analyze the concept of the constrained equation of the dynamic system: For the rigid system, there is a hinge (or motion vice) between the rigid body.

If the action is repetitiveOr with vision and other sensors, it can be predictable. Several position memory points can be added to the control. Each point is marked with the end (manipulator), and each point has a joint position memory. If possible, it can also be a multi-joint time series memory.

They describe the relationship between different physical quantities respectively, so they have different meanings in practical applications. In addition, the calculation methods and application scenarios of the speed Jacobi matrix and the force Jacobi matrix are also different.

Jacobian matrix is an important concept in the system of differential equations, which describes the relationship between the rate of change of the function at a certain point and the rate of change of the independent variable at that point. In robotics and control systems, the Jacobian matrix is usually used to describe the relationship between the state change of the system and the input change.

Exercise is not only completed by the exercise system, but also by the control and regulation of the ___ system.

1. The coordination of multiple groups of muscles can only be completed. Exercise is not completed by the exercise system alone. It requires the control and regulation of the nervous system. It needs the supply of energy, so it also needs to be digested. The cooperation of system, respiratory system, circulatory system and other systems.

2. Motor system; nervous system; energy; respiratory system; circulatory system; circulatory system Test analysis: The human body is a unified whole. Exercise is mainly completed by the motor system, but it requires the control and regulation of the nervous system, as well as energy supply and respiratory system, circulatory system and consumption The cooperation of the chemical system, etc.

3. Transport more waste, so exercise is not done by the exercise system alone. It requires the control and regulation of the nervous system. It needs energy supply, so it also needs the cooperation of the digestive system, respiratory system, circulatory system and other systems.

4. Animal movement is not only done by the movement system. It requires the control and adjustment of (the nervous system). It needs (energy) supply, so it also needs the cooperation of (digestion) system, (vascular) system, (respiration) system, etc.
