【Abstract】 WT5BZ]A PID controller design method that achieves high performance for a wide range of linear self regulating processes is proposed. Satisfactory dynamic characteristic can be obtained for processes with various dynamics, including those with low and high order, small and large dead time, and monotonic and oscillatory responses. The method is developed based on a second order plus dead time modeling technique and a closed loop pole allocation strategy through the use of root locus. The model is proven to be effective for a wide class of processes, and the model is able to generate peaks in those of oscillatory processes. Different closed loop poles are selected according to the damping ratio and dead time, and simple formulas are provided for the calculation. Simulation show satisfactory results. [WT5HZ]更多还原
