detour compensation

Introduction

The Zigzag compensator (also known as the return path compensation method) is a popular engineering method used to correct the displacement caused by zigzag of a precision moving axis or other rotary or linear motion system. This method is suitable for applications such as vision tools, robot manipulators, resonance and high frequency compensation machining systems and gas free laser cutting system. The principle of this method is to form an opposite phase shift and amplify the tracking object, after the phase difference between the two components becomes zero, the system can be artificially adjusted, the driven object can perform the ideal linear motion, and restore the normal operating conditions.

Advantages of Zigzag Compensator

The Zigzag compensator is suitable for fast and accurate tracking of small movement, even for large displacement. During the operation of an engineering system, the accuracy and high speed of the movement determine how high the tracking accuracy can be. The Zigzag compensator can ensure that the displacement value of the system remains accurate, using a small angle to make very precise adjustments.

In addition, the Zigzag compensator can reduce the energy wasted when the drive system is operating. In many traditional motion control systems, especially DC motors, the systems output power will be greatly reduced if the friction force increases. This friction force can be further reduced by the use of the Zigzag compensator, resulting in less power wastage and an increase in efficiency.

Disadvantages of Zigzag Compensator

The main disadvantage of Zigzag compensator is the complexity of its design. Because the design must take into account multiple elements, including the flexural stiffness of the drive shaft, the moment of inertia of the drive system, the strength of the magnetic field, etc., the design process can be rather complex and time-consuming. This can make it difficult for designers to execute it quickly and accurately.

Furthermore, a proper design must also consider the various motion characteristics of the drive. The motion characteristics, such as the frequency of vibration, smoothness of the motion, etc., can have a significant impact on the accuracy of the entire system. Therefore, it is important to determine these motion characteristics at the design stage in order to achieve the desired system performance and accuracy.

Conclusion

The Zigzag compensator has many advantages in engineering systems, such as fast and accurate tracking of small movements, precise adjustments for large displacements, and reduced energy wastage. However, the disadvantages should not be ignored. It requires complex design process and consideration of different motion characteristics, both of which contribute to the difficulty of the design process. Overall, with proper design and implementation, the Zigzag compensator can be highly effective for engineering applications.

Backing up is one of the most important driving techniques taught in Driver’s Education classes. It also one of the most difficult, as it requires finely tuned coordination and a level of accuracy to succeed. An advanced method of backing up, known as ‘back up and compensate’, can be used to aid in the successful execution of backing up.

Back-up and compensate uses tiny, rhythmic twice movements with the steering wheel that help guide a vehicle in a set path. The process begins with the first turn. Instead of turning the wheel the full ninety degrees, the driver slowly and smoothly turns the wheel slightly and begins their backing up manoeuvre. Once this first turn is complete, the driver begins to move the vehicle and very quickly turns the wheel in the opposite direction for a second time. This second turn compensates for any loss of accuracy due to the first turn, and helps to keep the vehicle in the desired path. The vehicle is then moved for a few feet, and then the compensation turn is made again. This process is repeated until the backing up is complete.

Back-up and compensate can help keep the vehicle on path and can eliminate the additional turns normally made to try to compensate for mistakes. It is a helpful technique that can be used in a variety of situations when backing up is required. It is important to practice the technique in a safe environment to become proficient in its use, such as an empty parking lot. It is also important to practice with both right and left turns, as well as varying vehicle speeds and distances. Mastering back-up and compensate will help make the backing up process more efficient and accurate.
