We want to solve for the ratio of ys to us, so we need so remove qs from the output equation. Hand in hand with this viewpoint was the feeling that many of the approaches useful for linear systems ought to be extensible to the nonlinear theory. Introduced the notions of controllability and observability.
The emphasis of this tutorial on control theory is on the design of digital controls to achie ve good dynamic response and small errors while using signals that are sampled in time and quantized in amplitude. The approach is supported by a geometrical illustration of systems evolution in the state space, by the lyapunovs direct method, the native behaviour of the controlled process, and the desired system matrix.
