The system under consideration involves state timedelay, control input time delay, parameter uncertainties and unknown nonlinear disturbances.
系统包含状态时滞、控制输入时滞、参数不确定性和未知的非线性扰动。
2
Temperature and humidity control object of artificial climate chest is a nonlinear, strong coupling and long timedelaysystem, so its control is difficult.
人工气候箱温湿度控制对象是一个非线性、强耦合和大滞后的系统，其控制非常困难。
3
Since the temperature system of humidifier is a large time-delay nonlinear system, the normal PID control can not achieve the desired performance.
