Abstract:

A method of design is developed for nonlinear sampled-data systems in which the single control input signal to the linear plant is quantized to 3, 5, 7... levels. Time responses for certain designs were computed and compared with the wellknown bang-bang or two-level systems. The use of five or more levels enables the designer to obtain good static accuracy as well as good dynamic performance. The designs are suited to instrument sampled-data systems where good control is required with a minimum number of allowable levels of the control signal. Simple switching circuitry can be used to realize the system when the sampled state variables are quantized to a satisfactory number of levels. Author
