摘　　要：针对双容水箱液位控制系统单输入、单输出、时变、非线性、耦合和滞后的特征,以双容水箱液位为被控对象,设计基于状态方程模型的MPC预测控制器,对水箱液位进行控制。仿真结果表明:该控制器可以满足模型多输入、多输出、精确控制、抗干扰、耦合和非线性特征的控制需求,比传统PID控制器有更明显的优势。Aiming at characteristics of single input and output, time-varying, nonlinearity, coupling and hysteresis, the level of double-tank system was taken as the controlled object;and considering the model’s nonlinearity, coupling and hysteresis, a state equation model-based MPC was designed for the tank level.Simulation results show that, compared to the traditional PID controller, this controller can satisfy the control operation like multi-input and output, accuracy control, anti-interference, coupling and nonlinearity.
