摘　　要：针对锂电池恒流放电控制系统的大惯性、非线性和大滞后性等问题,设计了一种基于模糊控制算法的自动控制系统。该系统以单片机Mega128作为主控芯片,运用PWM脉宽调制技术对锂电池的放电电流进行控制。实验证明,该系统可以迅速响应电流变化,且运行稳定可靠,可广泛地应用于各类锂电池的生产和容量检测场合。In view of nonlinear, strong inertia and heavy delay questions of lithium battery constant current discharge system, a control system based on fuzzy was designed. System based on the single chip computer Mega128 as the master control chip, using PWM pulse width modulation technology to control lithium battery discharge current. The experimental results show that the system can quickly response current change, operation is stable and reliable. It can be widely used in all kinds of lithium battery production and capacity testing occasions.
