<p>A method for shaping the time responses of a controlled physical process comprises the step of tuning selected gains of the process for shaping the time responses output from the process. In particular, additional inputs, outputs, and sensors (105, 106) are added to the controlled physical process (101) and are connected to memory elements (107-109) and to an optimizing computer (110) through data-path switches (S1-S5). A series of experiments generates the process time responses and the response sensitivities for storage in memory. Desired process time responses are created and stored in read only memory (112) of associated apparatus. An objective function is formed as a summation of the two-norms of weighted process time response errors. The response sensitivities are used to form a quadratic approximation of the objective function. The optimizing computer is used to minimize this approximate objective function subject to gain constraints. The new gain values are used in the controlled physical process to obtain the new process time responses. The desired process time responses, weightings, and gain constraints are modified and new approximations of the objective function are formed and minimized until process time responses are achieved that satisfy the design requirements.</p> |
