本文讨论了磁盘存贮器伺服定位系统的存取控制系统的分析与设计原则。讨论了随机存取的统计平均运动时间和系统参数(质量 M,最大运动距离 L,加速度 a,最大速度 V_m,驱动电机峰值功率 P_m)之间的关系,指出了进一步缩短运动时间的途径。从最佳过渡过程的观点给出了电机的设计步骤,为电机磁路设计提供了参数。本文还讨论了最佳过渡过程实现的一些主要具体问题。比较了电压开关和电流开关功放的利弊。确定工程上采用电压开关比较有利,还计算了理论的刹车函数,以及工程上装订刹车函数的方法。最后还给出了实际寻道的实测波形。
This article discusses the disk storage servo positioning system access control system analysis and design principles. The relationship between statistical average movement time of random access and system parameters (mass M, maximum movement distance L, acceleration a, maximum velocity V_m and peak power P_m of the driving motor) is discussed, and the way to shorten the movement time is also pointed out. From the perspective of the best transition process, the design procedure of the motor is given, which provides the parameters for the design of the magnetic circuit of the motor. This article also discusses some of the key specific issues that are best achieved in transitional processes. Comparing the pros and cons of voltage switches and current switching amplifiers. It is more advantageous to use the voltage switch to determine the engineering, and also to calculate the theoretical braking function and the method of binding the braking function on the project. Finally, the actual waveform of the actual seek is given.
