Systems In order to understand the current mechatronic servo system and develop servo systems with better performance than at present, this servo system must be investigated from various points of view The discussion points are listed as below 1 2 3 4 Modeling of a mechatronic servo system Performance of one axis in a mechatronic servo system Performance of multiple axes in a mechatronic servo system Command... Command to servo system The above viewpoints come from the system components of servo system in theory It means that a servo system is one of the system components for establishing a mechanism machine and needed to know that in which step servo system can be thought as good enough so that the system is constructed efficiently, desired mechanism as well as performances is realized, etc Therefore, the description... description is given in section 2.3 The discussed modeling combining the modeling of the whole servo system in the former part, the importance of modeling control system in future mechanism machines is illustrated 1.2.2 Discussion on the Performance of One Axis in a Mechatronic Servo System In a usual, mechatronic servo system consists of multi-axis mechanism When taking into account the performance of a mechanism... various control properties of the mechatronic servo system can be analyzed and they can be adopted in the design of the servo controller 2.1.1 Mechatronic Servo Systems (1) Structure of an Industrial Mechatronic Servo System Fig 2.1 illustrates the whole structure of a mechatronic servo system As shown in this figure, the industrial mechatronic servo system is the servo system including the mechanism part,... remember the solution whose roots must be definitely used in a mechatronic servo system The command method adopted in this book is not only introduced in this chapter, but also considered for the performance improvement of the 1.2 Issues in Mechatronic Servo Systems 15 future mechatronic servo system The command method to the servo system, considering the properties of mechanism, the features of disturbance... The so-called mechanism machine (called as mechatronic servo system at the following), i.e., the servo system adopted in the numerical control machine or industrial robot, is generally different from the servo system introduced in the textbook of automatic control, which is very important when discussing the mechatronic servo system Firstly, the control pattern assigned in mechatronic servo system is... control is explained in section 7.2 1.2.4 Discussion on the Command of Mechatronic Servo Systems For improving the motion performance of the whole mechatronic servo system, the method for providing the command to the servo system at each moment is a very important factor It means that the final desired motion of current mechatronic servo systems should be approximated from the known information before... this servo system is combined into each axis corresponding to the mechanism part That is to say, in an industrial mechatronic servo system, the discussion on servo system is carried out for only one axis, because of the importance of the servo problem for each axis If this one axis problem can be solved, the general industrial mechatronic servo system problem can be solved, when each axis of an industrial... performance, which component of control system should be improved is also unknown In section 3.1, the quite simple form of mechatronic servo system was analyzed The relation between the performance of a control system and sampling time interval when considering the utilization situation of a servo system was clarified (2) Reference Input Time Interval When considering the characteristic of a mechatronic servo . of multiple axes in amechatronic servosystem 4.
